Helium has several unique characteristics that make it advantageous for welding applications. Its high ionization potential, high thermal conductivity and inertness offer benefits—such as higher travel speeds and better quality welds—that can translate into greater productivity and reduced labor costs.

Helium offers advantages for Gas Metal and Gas Tungsten Arc Welding
From the manufacture of lawn chairs to tank trucks, from boats to rocket ships, gas metal arc welding (MIG) or gas tungsten arc welding (TIG) applications that can benefit from using helium as a shielding gas. Compared to pure argon, helium can provide:

• Better shielding gas coverage
• Higher travel speeds
• Greater weld penetration of thick metals and metals with high thermal conductivity such as aluminum and copper
• Increased deposition without preheating
• Improved performance over mild contamination
• Flatter surfaces for reduced cleanup
• Greater safety with reduced fume and spatter

Air Products' Maxx® shielding gases for carbon steel, stainless steel or aluminum welding can help to improve productivity and minimize ozone exposure.

We offer gases for plasma arc welding
Air Products offers helium and other gases for plasma arc welding applications such as welding butt joints in plates or pipes.

Look at helium's benefits for laser welding
Helium offers advantages for laser welding in such automotive manufacturing applications as tailor welded blanks, auto body assembly and manufacture of components such as airbags, transmissions and exhaust systems.

Helium is less likely to ionize than argon; when it is used as a shielding gas for molten weld pool, it helps suppress plasma formation, resulting in higher travel speeds. Helium also offers protection from oxidation, and it protects the laser system's optics.

Helium can also be used to cool the lasing gas in CO₂ lasers.
