How nexAir’s Gas Supply Solutions Impact Metal Fabrication and Welding Quality

In metal fabrication and welding, shielding and cutting gases do more than just protect the weld—they directly influence quality, efficiency, and overall project success. The correct gas supply is crucial in delivering strong, clean, and consistent results, from achieving precise weld penetration to reducing spatter and improving arc stability. nexAir provides high-quality gas solutions tailored for fabrication shops, manufacturing plants, and independent welders, ensuring a steady and reliable supply that enhances both productivity and performance.

Gases in Metal Fabrication and Welding

Every welding process has specific gas requirements that affect how the weld pool forms, how much oxidation occurs, and the overall strength of the final product. Different gases and gas blends serve distinct functions, making it important to choose the right one for the job.

• Argon: Used primarily in TIG and MIG welding, argon provides excellent shielding for non-ferrous metals like aluminum, preventing oxidation and ensuring clean, precise welds.
• Carbon Dioxide (CO₂): A common choice for MIG welding, CO₂ enhances penetration and is cost-effective, though it can produce more spatter than mixed gases.
• Argon-CO₂ Blends: This combination balances arc stability and spatter control, improving weld quality for mild steel applications.
• Helium Mixes: Often used for high-heat applications, helium improves weld fluidity and increases travel speed.
• Oxygen-Enriched Blends: A small percentage of oxygen added to argon or CO₂ can enhance arc performance and penetration in stainless steel welding.

Beyond shielding, gases are also essential for cutting and purging applications. Oxy-fuel cutting requires precise oxygen delivery for clean metal separation, while inert gases like nitrogen and argon are used in purging stainless steel pipes to prevent contamination inside the weld zone.

Why a Steady Gas Supply Matters

Running out of shielding gas in the middle of a weld can lead to oxidation, porosity, and weak joints, causing rework and delays. A steady and reliable gas supply is critical for maintaining high-quality output and avoiding unnecessary downtime. nexAir offers flexible supply solutions, including:

• Bulk Gas Deliveries: Ideal for high-volume fabrication shops that need continuous access to shielding and cutting gases.
• Cylinder Exchange Programs: A convenient option for smaller operations that need consistent gas replenishment without managing bulk storage.
• On-Site Gas Generation: For large-scale production environments, on-site gas generation systems can improve efficiency and reduce reliance on external deliveries.

With these options, welders and fabricators can focus on their work without worrying about supply chain interruptions.

Enhancing Quality and Efficiency with nexAir Solutions

Using the right gas blend is just one part of the equation—ensuring purity, proper flow rate, and consistency across all applications is just as important. nexAir provides high-quality gases with precise mixing and storage solutions to prevent contamination, fluctuations, or inconsistencies affecting weld integrity. Our solutions help:

• Improve arc stability and penetration
• Minimize rework caused by oxidation or spatter
• Increase travel speeds for faster, more efficient welding
