You can use tungsten inert gas (TIG) and metal inert gas (MIG) welding to make high-quality joints between different types of metal. Neither option is superior overall, but the unique welding techniques and processes will suit different jobs better. 

MIG welding is generally less complex and penetrates thicker materials more effectively, whereas TIG welding is ideal for precise welds on thinner materials. Explore the similarities and differences between MIG and TIG welding and when to use each type. 

TIG vs. MIG Welding

TIG and MIG welding techniques are similar, but have key distinctions to be aware of before choosing one over the other. Important differences include: 

  • Cost: MIG welding is faster, so it can be more cost-effective in terms of labor costs and productivity. The machines, parts and the wire required for MIG welding are usually easier to source and less expensive than TIG parts.
  • Process: While both use arc welding, the process is different, and you need specific welding equipment and tools for each type. This includes the electrodes used, the need for separate welding rods, foot pumps and power sources. 
  • Weld strength: TIG welds can be stronger because they use a narrower arc for better penetration into the metals. They can also be tougher because they can have fewer defects.
  • Application: TIG welds use a handheld filler rod, which allows for more accurate joins. However, this means using two hands and a foot pedal. This makes TIG welds better for workbenches and static setups, whereas MIG welding gives you a free hand for awkward joins or for site work.
  • Ease of use: MIG welding is easier to learn, partly because less equipment is needed, and one hand is always free. 
  • Precision and aesthetics: For fewer spatters or discolorations, choose TIG welding for less cleanup work. MIG welds can still be done carefully to preserve aesthetics, and you can polish up any blemishes after welding. 
  • Automation: MIG torches or guns are often compared to hot glue guns, have an automatic arc and can be run continuously. TIG welding requires operators to adjust the amperage to control the heat needed to melt materials.
  • Gas flow: Depending on the materials, TIG welding can use a lower gas flow rate than MIG welding.
  • Power source: MIG techniques use direct current (DC) power for stability and can penetrate most metals. TIG can use alternating current (AC) or DC power to suit the type of metals, electric arc and weld pool spatter.

MIG and TIG welding both follow a similar process to arc welding. This involves an electric arc or current that heats up and melts the metals or base materials you want to join together. You can also use filler materials in both MIG and TIG welding to help strengthen the bonds. 

Heating the base materials and filler creates a pool of molten material, which then cools to form a solid, clean joint. The shielding gas protects materials from contamination or oxidation. Both types of welding can be used across different industries, from manufacturing and construction to aerospace and marine.

TIG Welding Process

TIG welding, also known as gas tungsten arc welding (GTAW), uses a non-consumable tungsten electrode to heat up and melt the parent materials and filler materials used to create a joint. 

The foot pedal controls the heat by setting the correct amperage for the materials you’re working on. With the welding electrode in one hand, add the filler material with the other using a welding rod placed into the welding pool. 

The best practice is to use argon as the shielding gas, as it is the most affordable and accessible of inert gases. Argon protects your weld from defects caused by oxygen and nitrogen contamination. 

Benefits and Applications of TIG Welding

TIG welding can be more effective for some applications, including:

  • Thin metals: TIG welding can be less aggressive on thinner gauge metals, which helps prevent warping or burning through the material. It is also possible to make autogenous welds with no need for filler material. You can use a lap joint weld to join the parent materials together.
  • Exposed beads: TIG welding can give a better finish for cleaner, more aesthetic welds. This is useful for consumer products or when beads are exposed.
  • Ferrous and nonferrous Metals: Typically, TIG welds join steels and nonferrous metals, such as aluminum and copper. 
  • Workshop welding: Outdoor windy conditions can interfere with TIG welds. Instead, TIG welding is better for precision jobs in a workshop environment where the control of the filler rod and foot pedal is more beneficial. 

MIG Welding Process

Also known as gas metal arc welding (GMAW) or wire welding, MIG welding uses a consumable solid wire electrode. The wire acts as both the electrode and the filler material here. Constantly feed the spool of wire through the welding gun into the weld pool, where it is heated, melting the parent material and adding a filler material to help join them together.

You can also use argon as a shield gas for MIG welding, with the option to add carbon dioxide. The added CO2 prevents oxidation and allows for short arc transfer or dip transfer welding, which allows for welding in various positions. 

Benefits and Applications of MIG Welding

MIG welding offers many benefits, including the following:

  • Suitability for diverse operations: MIG techniques are suited to a wide range of materials, thicknesses and welding positions for when you need versatility in your welding operations. 
  • Covered welds: When aesthetics are less important, such as in structural applications, MIG welds are durable, and you can paint or cover them if needed.  
  • Quick production times: MIG welding is efficient and often faster than TIG welding, so you can reduce lead times and labor costs. 
  • Thicker materials: MIG welding can handle different thicknesses and gauges, but it is more effective for welding thicker materials. This is because MIG offers higher deposition rates and deeper penetration into the materials.
  • Training new hires: MIG welding is less complex to learn, making it easier for beginner welders to create acceptable welds while maintaining production speed.

A welding test is a critical component of quality assurance. It ensures that welded joints meet structural integrity, performance and safety requirements. Inspectors evaluate welds based on predefined criteria to detect defects that could compromise a product or structure. 

A successful welding inspection depends on rigorous preparation, adherence to technical specifications and thorough documentation. This guide from Meritus Gas Partners will help you pass a welding inspection by providing timely, relevant and code-compliant support.

By following these steps, welding teams can demonstrate quality work, comply with applicable codes and confidently pass inspections. This structured approach also supports traceability, quality assurance and long-term welded component performance. 

Understanding Welding Inspections in Manufacturing

Welding inspections verify that welds conform to design specifications, industry codes and applicable standards. They help prevent failures in critical infrastructure, including pipelines, bridges, pressure vessels and structural steel. Inspection can occur before, during and after welding. This phased approach allows for real-time quality control and timely corrective actions. Types of welding inspections include:

  • Visual inspection (VT): VT is the most basic and widely used method. Inspectors check for surface defects such as cracks, undercuts, porosity and misalignment. Visual inspection is often the first step in any quality control process.
  • Radiographic testing (RT): RT uses gamma rays or X-rays to detect internal defects. This method provides a permanent weld image and can identify porosity, slag inclusions and cracks. It is commonly used in pressure vessel and pipeline fabrication.
  • Ultrasonic testing (UT): UT sends high-frequency sound waves into the weld and analyzes the echoes that return. This method is highly effective for identifying internal flaws and measuring weld thickness. It is suitable for thick materials and critical applications.
  • Magnetic particle testing (MT): MT is used on ferromagnetic materials. Inspectors apply a magnetic field and then introduce fine iron particles. Surface and near-surface defects disrupt the magnetic field, attracting particles and indicating flaws.
  • Liquid penetrant testing (PT): PT reveals surface-breaking defects. A colored or fluorescent dye penetrant is applied to the weld surface and then removed. A developer draws out the penetrant trapped in defects, making them visible.
  • Destructive testing: In some cases, inspectors cut and physically test welded specimens to evaluate mechanical properties such as tensile strength, ductility and impact resistance. Methods include bend testing, tensile testing and macro etching.

Common Welding Codes and Standards

To pass a welding inspection, it’s essential to understand the welding codes and standards that govern the work being evaluated. Welding inspectors use these documents to assess whether a weld meets the required quality, safety and performance criteria. The most commonly referenced codes and standards vary by industry and application, but they all serve as the technical foundation for inspection criteria.

American Welding Society (AWS)

AWS publishes widely used codes across structural, sheet metal and pipe welding. These codes establish minimum requirements for weld quality, procedure qualification, welder performance and inspection codes:

  • AWS D1.1: The structural welding code for steel is one of the most frequently applied codes in the U.S. construction industry. It covers welding requirements for steel structures, including buildings, bridges and towers.
  • AWS D1.2: The structural welding code for aluminum governs welding practices for aluminum structures, addressing materials, qualification and inspection.
  • AWS D1.3: The structural welding code for sheet steel applies to thinner materials, such as light steel used in HVAC and framing applications.
  • AWS D17.1: The fusion welding code for aerospace applications specifies the requirements for aerospace welding, where tight tolerances and high reliability are critical.

American Society of Mechanical Engineers (ASME)

ASME codes are predominantly used in pressure vessels, boilers and piping applications. Section IX defines the rules for qualifying welding and brazing procedures and personnel. B31.1 provides design and fabrication rules for high-pressure and industrial piping systems. It references Section IX for welding qualifications.

American Petroleum Institute (API)

API codes are prevalent in the oil and gas industry. API 1104 covers pipeline and related component welding in cross-country and gathering systems. It includes details acceptance criteria for weld discontinuities.

International Standards

Outside the U.S., many industries use standards from ISO 9606, which references welder qualification testing to ISO 15614 for welding procedures specification and qualification. Another frequently referenced standard is EN 1011, which offers welding guidelines for metallic materials. These international standards may also be required for projects with global clients or regulatory requirements. 

Key Criteria Inspectors Evaluate 

Understanding and applying the correct welding codes is critical to passing inspection. Each code provides a clear framework for what constitutes an acceptable weld. Inspectors rely on these standards to assess workmanship, verify compliance and ensure safety and reliability. Welders, engineers and quality personnel should be trained and qualified to the applicable code to ensure project success and compliance. Inspectors evaluate welds based on specific acceptance criteria outlined in welding codes and standards.

Here is what inspectors look for in a weld:

  • Visual inspection: Inspectors assess surface defects such as cracks, porosity, undercut, incomplete fusion or overlap.
  • Dimensional inspection: Weld size, length and placement are assessed to ensure they meet the drawing and code requirements.
  • Nondestructive testing (NDT): Techniques such as RT, UT, MT and PT are used to detect internal or surface-breaking discontinuities.
  • Procedure and personnel qualifications: The welding procedure specifications (WPS) and welder qualifications must be documented and comply with code requirements.
  • Materials and traceability: The correct base materials, filler materials and consumables must be used. Material certificates and heat numbers should be traceable.

The Role of Gases and Consumables in Welding Quality

Gases and consumables directly affect arc stability, metallurgical properties, penetrations and the overall weld integrity. Understanding how they contribute to the welding process is critical to meet code requirements and ensure a successful inspection outcome.

Shielding Gases

Shielding gases protect the molten weld pool from atmospheric contamination. Oxygen, nitrogen and hydrogen in the atmosphere can cause weld defects such as porosity, cracking and oxidation. The type and composition of the shielding gas affect arc characteristics, weld penetration, bead shape and mechanical properties. Common shielding gases are:

  • Argon (Ar)
  • Carbon dioxide (CO2)
  • Argon and CO2 blends
  • Helium (He)
  • Oxygen (O2) or Hydrogen (H2) additions

Filler Metals

Filler metals provide the deposited metal in the weld. Their chemical composition must match or complement the base metal to ensure mechanical integrity and corrosion resistance. Filler materials are classified by standards such as AWS. They can include consumables such as stick electrodes (SMAW), solid wires (GMAW), flux-cored wires (FCAW) or tungsten electrodes (GTAW). 

Fluxes and Slag Systems

In processes like SMAW, FCAW and submerged arc welding (SAW), flux plays a vital role in shielding, alloying and slag formation. Slag protects the weld pool and must be properly removed between passes. 

Best Practices for Ensuring Weld Quality

Improper gas and consumable selection or handling can compromise structural integrity, leading to inspection failures or service defects. For high-quality, code-compliant welds, gases and consumables must be managed with precision, aligned with procedure requirements and handled using best industry practices:

  • Use the appropriate shielding gas and flow rate for the process and material.
  • Select the right filler metal based on the base metal, welding position and service conditions.
  • Store consumables in dry, controlled environments and use ovens for low-hydrogen electrodes.
  • Check the material certificates for batch traceability and compliance with WPS.
  • Perform pre-weld checks to verify gas supply purity and consumable condition.                                                 

Preparing for a Welding Inspection: Step-By-Step Guide

Preparing for a welding inspection requires a methodical approach that ensures compliance with applicable codes, procedures and quality requirements. The steps below outline how to effectively prepare for a welding inspection by leaning into technical accuracy and inspection readiness.

Step 1: Review Applicable Codes and Specifications

Before any welding starts, identify the governing welding code and project specifications. These documents define weld joint design, qualification requirements, acceptance criteria and inspection methods. Verify that the current code condition is used, clarify project-specific amendments, and understand weld quality acceptance limits for discontinuities such as porosity, undercut or incomplete fusion.

Step 2: Verify Welder and Procedure Qualifications

Ensure that WPS and welder performance qualifications (WPQs) are approved and up to date, matching welder qualifications to joint type, position and material group. It is also imperative to maintain records of WPS, procedure qualification records (PQRs) and WPQ in a traceable format for reference during inspections.

Step 3: Check Materials and Consumables

All base metals, filler metals and gases must conform to the approved WPS and relevant code requirements. It is essential to:

  • Confirm that material test reports (MTRs) are available and traceable.
  • Inspect filler metal certificates.
  • Verify proper wire and electrode storage.
  • Confirm shielding gas type and purity, and check for adequate gas supply.

Step 4: Confirm Joint Preparation and Fit-Up

Joints must be prepared according to the WPS and drawing requirements before welding. Measure joint dimensions, including the root opening, bevel angle and land, using approved gauges. Ensure surfaces are clean and free from rust, oil and other contaminants. Also, check the applicable backing bars, inserts or consumable backing. 

Step 5: Verify Welding Equipment and Settings

Welding machines and equipment must be calibrated, maintained and configured as required by the WPS. This includes confirming amperage, voltage, wire feed speed and travel speed while checking polarity and shielding gas flow rate. Inspect contact tips, nozzles and ground clamps for wear and damage. 

Step 6: Perform In-Process Inspections

During welding, maintain quality control by monitoring parameters and workmanship:

  • Use calibrated tools to verify interpass temperature and heat input.
  • Monitor for arc length, travel angle and welder technique.
  • Remove slag between phases as needed.
  • Conduct a visual inspection of each pass before proceeding.

Step 7: Conduct Post-Weld Cleaning and Inspection

After welding, prepare the weld for final inspection by removing slag and spatter. Clean the weld using wire brushing or grinding per code requirements. Check for cracks, overlap, porosity, undercut and other surface defects. Measure the weld size, length and location against the WPS and drawing, documenting all visual inspection results.

If the weld’s nature requires an NDT test, this may also be the right time. Provide the inspector with access to welds and remove surface contaminants as required. Then, review the NDT reports for compliance with acceptance criteria.

Common Reasons for Inspection Failure

The key to maintaining compliance, avoiding costly rework and ensuring long-term performance stems from understanding why welding inspections fail:

  • Weld defects or discontinuities that result from incorrect travel speed, heat input, improper technique or contaminated base metals
  • Unqualified welders or procedures, which are classified as procedural failure instead of a weld failure
  • Inadequate joint preparation and fit-up from rushed or inconsistent fit-up practices
  • Improper consumable handling, such as using expired low-hydrogen electrodes or substituting consumables without confirming compatibility
  • Incomplete or missing documentation, including MTRs, PQRs, WPS and NDT results
  • Failure in post-weld cleaning and inspection, which can conceal weld defects or cause discontinuities

Most inspection failures are preventable through proper planning, skilled labor and strict adherence to procedure. Partnering with knowledgeable local distributors and technical experts significantly increases your chances of passing the welding inspection. It helps bridge the gap between code requirements and real-world applications, ensuring your welding operations meet quality standards the first time.

How Local Expertise Helps You Pass 

Whether working on pressure vessels, structural steel or pipelines, partnering with knowledgeable local distributors and technical experts can significantly improve the reliability and quality of welding operations. Distributors often maintain a local inventory of high-quality consumables and equipment, reducing lead times and supply chain disruptions. Local welding experts are familiar with the specific codes, standards and regulatory requirements that apply in specific areas or industries, including:

  • Local building codes or jurisdictional amendments to AWS, ASME or API standards.
  • State, municipal or owner-specific inspection criteria.
  • Common inspection practices used by regional certifying bodies or third-party inspectors.

For example, if a welding application calls for low-hydrogen electrodes like E7018, a local distributor can advise on correct storage, reconditioning and handling practices that prevent moisture pickup and hydrogen-induced cracking — two common causes of inspection failures.

Laser welding is a cutting-edge technique for joining metals and thermoplastics that has revolutionized the manufacturing and engineering industries. Unlike conventional welding techniques, laser welding offers exceptional speeds and can effectively weld many different materials, from steel to acrylic.

Understanding the Role of Lasers in Welding

Laser welding uses a highly concentrated beam to rapidly heat a small area to melt the material and form a molten pool. As the pool cools, it fuses the materials to create a strong bond. 

Laser welding is a more effective choice than traditional options like spot and arc welding for several reasons:

  • Arc welding is a joining process that uses electricity to create a temperature arc to melt and fuse metal. Unlike arc welding, laser welding uses a focused laser beam to produce durable and aesthetically pleasing welds. 
  • Spot welding is an older method that joins metal sheets through pressure and current without filler materials. Laser welding is able to complete the same outcomes as spot welding more efficiently and provides the option for automation to streamline your overall operations.

There are also multiple laser welding techniques available, depending on your material and the desired result. These include the following.

Conduction Welding

Conduction welding uses the process of heat conduction to melt materials. As the laser beam hits the surface, it creates an even distribution of heat and causes the material to melt without penetrating the workpiece, making it ideal for materials with low melting points. Conduction welding is a great choice for industries sensitive to heat input and control in welding, such as jewelry, electronics and medical devices.

Keyhole Welding

Keyhole welding uses a high-energy laser to heat the material past the fusion point, causing it to melt and then vaporize. As the material vaporizes, it leaves behind a narrow cavity called the keyhole. The molten material then flows into it for a solid bond free from imperfections. 

Keyhole welding is ideal for thicker materials with higher melting points, making it a great choice for applications like aerospace and automotive manufacturing.

Key Benefits of Laser Welding

Laser welding is the latest in welding technology advancements and has become popular in industries requiring speed, precision and quality. 

Some of the many benefits laser welding provides are:

  • Material compatibility: Welds dissimilar materials like steel and aluminum, and some thermoplastics. The keyhole welding technique also allows for the penetration of thicker materials with minimal heat input.
  • Energy efficiency: Delivers heat directly to the weld seam to minimize the heat-affected zone and reduce thermal damage or distortion.
  • Cost reduction: Offers faster processing, higher production capacity and eliminates post-processing for greater time and money savings.
  • Automation integration: Seamlessly integrates into your existing automated production line to reduce the need for manual intervention and guarantee quality consistency.
  • Weld quality assurance: Provides precise alignment and cleaner seams to enable the welding of small or delicate parts without the risk of damage or distortion.

Industry Applications of Laser Welding

The precision, efficiency and versatility of laser welding make it a valuable tool across many different industries, including:

  • Aerospace: Laser welding can be used to create strong weld joints in turbine components and is beneficial for applications such as in-space manufacturing and repair.
  • Automotive: Manufacturers can form a strong bond with many automotive materials and metals through welding with minimal distortions. Some applications include tailored blanks, tubes and hang-on parts like doors and side panels.
  • Medical devices: Laser welding is beneficial in creating sensors, medical implants and other delicate devices that require strong bonds without affecting the components surrounding the weld site.
  • Jewelry: This type of welding is compatible with precious metals, like gold and silver, and can aid in creating intricate pieces or repairing and resizing jewelry.

Summer Welding Safety

When temperatures rise, so do the risks on the job. Summer welding isn’t just uncomfortable—it can be dangerous if you’re not prepared. Between high temps, heavy protective gear, and intense job site conditions, it’s easy to underestimate how quickly heat-related illnesses can set in.

At Atlas Welding Supply, we care about your safety year-round. As part of National Safety Month, here are three crucial tips to help welders beat the heat and stay safe this summer:

Stay Hydrated

Welding is physically demanding—and when you’re working in high temperatures, your body loses fluids fast. Don’t wait until you’re thirsty to drink water. Thirst is actually a sign you’re already dehydrated.

  • Keep a water bottle nearby and sip frequently throughout the day.
  • Avoid sugary drinks, soda, or energy drinks—these can worsen dehydration.
  • For long shifts in extreme heat, consider drinks with electrolytes to replenish what you’ve lost through sweat.

Dress Smart

It might be tempting to go lighter on protective gear in the summer, but safety should always come first. The key is to choose the right gear—not less of it.

  • Wear lightweight, breathable and flame-resistant clothing. Modern flame-resistant fabrics are designed to offer both protection and ventilation.
  • Opt for moisture-wicking base layers under your outerwear to keep sweat away from your body and help regulate temperature.
  • Never roll up your sleeves or leave skin exposed—sunburn and welding burns are a double threat.

Take Cool-Down Breaks

Overheating can sneak up fast—especially when you’re focused on a task. Regular breaks in the shade or a cooled indoor space can prevent heat exhaustion or even heat stroke.

  • Schedule short breaks every hour, especially during peak heat times (10 AM to 4 PM).
  • Use fans or cooling towels to help bring your body temperature down.
  • Know the signs of heat stress: Dizziness, nausea, confusion, rapid heartbeat, and fatigue. If you notice any of these, stop working and cool down immediately.

Weld Smarter, Not Harder This Summer

Your health is your most important tool—take care of it. A few smart precautions can help you power through summer projects safely and effectively. Whether you’re working in the field, in the shop, or on a remote site, Atlas Welding Supply is here to support your safety with the gear, gases, and knowledge you need.

Stay cool. Stay safe. And as always, weld on!

There are many welding techniques and processes, and some involve the use of compressed gases, also called shielding gas. Shield gases play an important role in welding, and it is crucial to understand how different types of gas influence welding outcomes and know how to choose the best one for your application.

What Are Shielding Gases?

Shielding gases shield or protect a weld from atmospheric contamination. Elements like oxygen, nitrogen and hydrogen can result in defects in the weld, so the shield gas acts as a protective layer between the environment and the weld puddle.

There are different types of welding gases, and they fall into two main categories:

  • Inert gases: Inert gases are inactive or nonreactive. This means they do not change or alter anything in the welding process — their role is more for protection and prevention against unwanted reactions with the atmosphere. The most common examples of inert welding gases are argon and helium.
  • Active gases: Active gases take an active role in the welding process, meaning they can exert influence over things like arc characteristics, weld pool fluidity and weld metal composition. In most cases, active gases are added or mixed with inert gases with a specific result in mind — improving arc stability, enhancing the weld bead profile or increasing penetration. Common active welding gases include carbon dioxide, oxygen and nitrogen.

Gas Mixtures for Different Types of Welding

Gases in their pure form may not always be right for certain welding applications. Some gases require mixing, while other gases can benefit from enhanced properties from mixing with others. Argon, helium and carbon dioxide gases operate well on their own or in mixtures. Meanwhile, oxygen, hydrogen and nitrogen work best when mixed.

Discover the best welding gas mixture ratios for different types of welding techniques:

MIG Welding Gases

Metal inert gas (MIG) welding, or gas metal arc welding (GMAW), is a traditional welding technique that uses an electric arc to fuse two metals together. MIG welding can use a wide range of inert, active and mixed gas options, such as:

  • Pure carbon dioxide: Carbon dioxide is common in MIG welds because of its cost-effectiveness and high penetration. On its own, it can work well for carbon steel welding, though it produces a more unstable arc and spattering, and is generally more effective in mixtures.
  • Pure argon: Argon provides good protection from atmospheric contaminants because of its weight. It is generally more stable and produces less spatter and penetration. It can be used in MIG welding for metals like copper, titanium or aluminum, but is more often mixed with other gases. 
  • Argon and carbon dioxide: Argon, known for its stability, works well in MIG welds when mixed with carbon dioxide, which can add heat and improve penetration. Common ratios for this mixture include 75% argon to 25% carbon dioxide or 90% argon to 10% carbon dioxide. This mixture is ideal for metals like carbon steel and mild steel. 
  • Argon and oxygen: One of the most common gas mixtures for stainless steel welding, argon and oxygen produce a stable arc, better penetration and a nicer weld bead. Most argon-oxygen mixtures for MIG welds involve 5% or less oxygen gas.

TIG Welding Gases

Tungsten inert gas (TIG) welding or gas tungsten arc welding (GTAW) is similar to MIG welding, except the filler metal is added to the weld pool separately from the arc. Argon is the most common and versatile gas in TIG welding, both on its own and in mixtures:

  • Pure argon: One hundred percent argon is most common in TIG welding because it is inert, has good arc stability and produces cleaner welds. Using high-purity argon can reduce contamination and produce higher-quality welds. It works with a wide variety of metals, including stainless steel, aluminum, titanium and aluminum alloys.
  • Argon and helium: This is the best gas mixture for aluminum welding, as well as nickel alloys and copper. Adding helium to argon helps tailor the weld for thicker materials or those with higher thermal conductivity. The most common ratios are 75% helium to 25% argon, or an even 50-50 mix.
  • Argon and hydrogen: While less common, an argon-hydrogen gas mixture can increase weld cleanliness and travel speed. Ratios often include 15% or less hydrogen, and these gas mixtures work best for TIG welding for stainless steel. Because of hydrogen’s volatility, special safety precautions are necessary.

In general, TIG welding tends to use pure argon except in cases that involve thicker materials or need a higher heat input to produce the desired results.

FCAW Welding Gases 

Flux-cored arc welding (FCAW) is another welding technique that uses shielding gas mixtures. The type of flux-cored wire dictates the appropriate shielding gas, so it is best to check with the wire manufacturer for the right recommendations. The shield gas for FCAW provides additional protection on top of that which is supplied by the flux core. Common shield gases for FCAW include:

  • Pure carbon dioxide
  • Argon and carbon dioxide

In some cases, a small amount of oxygen can be added to argon-carbon dioxide mixtures to increase arc stability and weld pool fluidity.

Shield Gas Welding Best Practices

To ensure a good weld, follow these best practices:

  1. Select the right gas: Different gases and gas mixtures have different chemical properties, which will affect how the welds turn out. Double-check that you are using the right gas for both the welding technique and the metal to get the results you want.
  2. Optimize gas flow: You can optimize gas flow with the right gas valve selection. Make sure the gas flow is appropriate to maintain proper weld quality while reducing waste.
  3. Use the proper regulator: Ensure consistent and safe gas delivery with the right regulator. Gas regulators are designed to strict safety standards to keep the gas flowing at the right pressure. When choosing a regulator, ensure it suits the type of gas you are using and can handle the inlet and outlet pressure for your application.
  4. Inspect equipment regularly: All equipment for gas welding should be properly maintained with consistent maintenance and regular inspections.

Safety and Regulations for Welding Gases

Working with compressed gases — whether you are performing complex welds or filling balloons for a party — requires special safety precautions. Refer to the Compressed Gas Association for the list of standards, and review these safety requirements for welding gases:

Handling and Storage

It is important to understand what kinds of gases you have in your facility, so check all canister labels before handling or storage. Be sure to refer to the safety data sheet for every gas you use.

Poorly handling compressed gas cylinders can result in leaks and explosions. The best way to transport gas for welding is with cylinder carts. If one is not available, it is best to roll the cylinder rather than attempting to carry it and risk dropping it. Store all cylinders upright in a well-ventilated area and away from direct sunlight or heat sources.

Ventilation and Respiratory Protection

When welding with shield gases, toxic gases and fumes are a dangerous by-product that pose risks to worker health and safety. Ensure the space is sufficiently protected for the kinds of welding activities — a local exhaust ventilation system provides the best protection when working with gases or high-intensity welds.

Personal protective equipment for welding is extensive. When working with gases, workers should use gloves, appropriate shoes, eye protection and ventilators. Though welders may already use respirator masks, make sure the ventilation is appropriate for the type of gas they are working with. 

Emergency Protocols

It is vital to have a plan in place in case of gas emergencies. Ensure all employees know how to report a gas leak and the proper procedure for handling gas exposure. Proper training and safe handling of gases is the best way to prevent emergencies, and it can ensure compliance with relevant safety regulations and standards.

Welding is a crucial part of the fabrication process. New technologies have broadened welding applications and techniques, allowing welders to enhance weld quality and efficiency. The innovations made by welding companies mean a bright future on the horizon. However, it’s essential to appreciate the fundamental components that make welding possible.

Gas regulators are vital to the welding process, yet many welders remain uncertain about how they work. All compressed gases pose risks, and regulators control their flow for safe and precise welding. With many different brands of gas regulators available, making the right selection for your application is even more essential.

Understanding Welding Gas Regulators

Welding gases create the heat and shielding needed to melt and fuse metals, and welding gas regulators are among the most important tools for any gas welding operation. These devices control the flow and pressure of gases used during welding by taking high-pressure gas from the cylinder and reducing it to a lower, stable pressure. They provide the consistency, quality control and safety needed for successful operations.

This control is critical because gases and applications require varying gas flow and pressure levels. For example, propane and acetylene gas regulators may have different requirements than argon and oxygen regulators due to their specific properties and welding applications. Choosing the best gas regulator requires a solid understanding of gas flow control.

Types of Gas Regulators and Their Applications

Matching different gases and their regulators means knowing which types are available so you can analyze their strengths, weaknesses and suitability. The most common types of gas regulators in welding include:

  • Single-stage regulators reduce gas pressure in one step to deliver pressure within a specific range. They’re often seen in cutting, brazing and other applications that require consistent pressure.
  • Dual-stage regulators reduce gas pressure in two steps, making them ideal for applications that require stable, precise pressure. Delivery pressure stays constant as the cylinder pressure decreases, providing greater accuracy in pressure control.
  • High-pressure regulators are built with heavy-duty components to withstand high-pressure gases.
  • Specialty regulators are designed for specialty, highly reactive gases. For example, acetylene regulators have a specific internal setup, as the gas can become unstable and explosive if compressed at high pressures.

Meritus Gas Partners has an extensive range of gas pressure regulators for welding. Our experts at any of our partner locations are happy to help you select the best option for your needs.

Selecting the Best Welding Gas Regulator for Your Needs

Once you understand the type, function and control of gas regulators, you can select the most suitable option for your application. The most crucial factor in any welding operation is the type of welding you do, as it influences every tool you select for the project. Some tips for regulator selection include:

  • Match the regulator and gas type: Each welding gas has specific pressure and flow requirements, which dictate the type of regulator. Speak to an expert to ensure you select a regulator compatible with your intended gas. The Compressed Gas Association has a standardized list of gas fittings to follow.
  • Consider the application: The type of welding you do will also dictate the regulator you choose. For example, oxy-fuel welding requires a high-pressure regulator, while tungsten inert gas welding requires a dual-stage regulator for better flow and pressure control.
  • Focus on flow rate and pressure range: Higher flow rates need a regulator to handle higher gas volumes. In contrast, lower flow rates often require a more sensitive, precise regulator. Regulators are designed to operate within certain pressure ranges. Consider your application’s inlet and outlet pressure requirements to ensure compatibility with your system.

At Meritus Gas, our team and partners are here to advise you on regulator selection. Contact an expert with questions to proceed confidently with your next project.

Troubleshooting and Maintaining Your Welding Regulator

Ensuring consistent and efficient gas regulator performance means regular maintenance, repairs and troubleshooting. The sooner you can identify the issue, the quicker you can complete the necessary repairs.

Effective welding performance relies on the consistent and controlled flow of the shielding gases. Gas flow issues can disrupt the process, leading to poor quality results, waste and even downtime. The following troubleshooting tips can help you mitigate the damage caused by inadequate gas flow:

  • Recognize the signs: You may notice symptoms in your weld that point to a gas flow issue. Look for excessive spatter, porosity, visible weld defects or an unstable arc. If you notice any of these things, you can act quickly to prevent further damage and waste.
  • Rule out the alternatives: The gas cylinder, nozzle or hoses could cause inconsistent gas flow. Before moving on to the regulator, check these components and replace them if needed.
  • Perform a flow test: Turn the welding equipment off, open the gas valve and watch the flow meter. Listen for any unusual sounds that might point to leaks or obstructions. Adjust the regulator to achieve the recommended flow rate for your application.
  • Assess regulator function: Verify that the regulator works correctly and displays accurate pressure readings. Look for signs of wear on the fittings that could cause leaks.
  • Check the flow rate: Ensure the flow meter and regulator are set to the correct flow rate for your application. An incorrect setting can impede gas flow or lead to unnecessary waste.
  • Evaluate equipment compatibility: Incompatible equipment can happen even in the most professional setting. A mismatched or poorly fitted regulator could be the culprit.

You can prevent many gas regulator issues with consistent preventive maintenance and timely repairs. Have a comprehensive cleaning and maintenance schedule for all welding equipment, and stay informed about welding equipment maintenance.

Whether you run a manufacturing plant or an industrial facility, downtime due to equipment malfunctions can cost up to 20% of your productive capacity. One way to minimize downtime is to ensure you can access a reliable welder.

Our guide explores different welding machines and their features. Learn how to select the right welder for the metal you use and which additional resources will help ensure project success. 

Understanding the Different Types of Welders

There are four primary welder types. Each machine has different power specifications and features to handle welding for different metals. While purchasing a multi-process welder is possible, single-process machines ensure more specialized applications.

Metal Inert Gas

Metal inert gas (MIG) welding, also called gas metal arc welding (GMAW) uses a machine encompassing a continuous wire electrode that you feed through the welding gun. When the wire and the metal come into contact, it creates an electric arc that melts the wire, effectively joining two metal pieces. MIG welders work with a shielding gas — such as CO2, argon or helium —  to protect the molten metal from air contaminants.

Technicians value this machine for its versatility, as it’s effective in welding aluminum, steel and stainless steel. However, your business needs to factor in the additional gas costs when calculating project expenses.

Tungsten Inert Gas

As the name suggests, tungsten inert gas (TIG) or gas tungsten arc welding (GTAW) uses a tungsten electrode to connect two mental components. These electrodes are nonconsumable, meaning they can withstand the heat of the electric arc and remain intact. Instead, the technician must add a filler rod, which melts to form the weld pool. One similarity between TIG and MIG welders is that they both require an inert gas to shield airborne impurities. 

TIG welding is a popular method for applications that require high precision — it ensures a cleaner finish, making it ideal for superior welds. One drawback to this process is that it’s more time-consuming than most, resulting in longer project times.

Flux-Cored Arc 

Flux-cored arc welding (FCAW) is similar to MIG in that it works with a continuous wire electrode. However, the tubular wire contains flux — a substance that assists in fusing metals and producing shielding gas.

FCAW machines are a good option for outdoor projects. They also effectively join many heavy-duty materials, even those affected by rust and corrosion. One important point to note is that FCAW is incompatible with some metals, such as brass and silver, making it less versatile.

Stick

Stick welding, otherwise referred to as shielded metal arc welding (SMAW), is a popular method that requires a flux-coated electrode to fuse metals. When the electrode meets the metal, it triggers an electrical arc, which melts both the electrode and the material. The flux coating melts in the process and releases a protective gas.

While stick welding requires a higher level of skill, it’s a preferred option for projects affected by wind and rain. It’s also a highly effective method for joining thicker metals for optimal strength.

Key Factors to Consider When Selecting a Welder

The type of welding you require will determine whether you need a MIG, TIG, FCAW or SMAW machine — yet there are some other factors to consider when choosing the right welder. Use these pointers to make a solid investment.

Material Compatibility

Welders are compatible with different metals, so you need to establish which material you primarily use. For example, the construction industry relies heavily on steel, making a MIG or stick welder a good choice. In comparison, the aerospace sector would benefit from a TIG machine since these businesses mainly work with aluminum and titanium.

A further material consideration is thickness. While some metals come in thin sheets — such as aluminum and copper — other materials are much thicker. Understanding the typical width of your material will help you choose the right machine size.

Duty Cycle 

A “duty cycle” is the length of time a technician can use a welder before it fails. To determine the approximate operation time, your business will need to know the machine amperage, or the charge that runs through the machine and impacts how much heat it produces during operation. If you work with thicker materials, you’ll require more amps to complete the project.

Voltage is another power requirement. It pertains to the force that propels the electric charge through the conductor. Smaller welding tasks require a voltage of approximately 110 volts, whereas industrial applications require machines with a 220 volts capacity.

Portability 

The location of your projects will influence whether you need a stationary or portable welder. For instance, if your team takes on welding tasks within a plant, there will likely be power outlets available to generate a consistent electrical current. However, if you typically handle projects in remote locations, selecting a battery-powered welder is a logical choice.

Both portable and stationary welders have pros and cons. Stationery machines generally offer more power, allowing you to work for longer and on thicker materials. However, unexpected power outages could lead to downtime. The clear benefit of battery welders is their mobility, yet you may have to sacrifice less power and stability.

Additional Equipment and Resources for Welding Success

Once you’ve selected your welder, your business will have a better idea as to which additional resources to purchase. Some common options include:

  • Shielding gas: Obtaining the correct welding gas will help you optimize your MIG and TIG processes. Purchasing gas from a reputable supplier enables you to access gas bottles with sophisticated vales and nozzles for better application. 
  • Personal protective wear (PPE): Ensuring your workers can operate welding equipment safely is a moral and legal obligation. From gloves to clothing and roll blankets, your staff should have the PPE they need. 
  • Robotics and automation: Technological advancements have led to collaborative robots, which help automate welding processes. Implementing this technology can help boost overall productivity and expand your bottom line.
