Shielding Gases

Argon and other shielding gas mixtures are used during the welding process to shield welds as they solidify, preventing oxidation. These gases significantly improve quality, reduce waste, boost productivity and decrease fumes.

• Gases for Gas Metal Arc Welding (GMAW)
• Gases for Flux-Cored Arc Welding (FCAW)
• Gases for Gas Tungsten Arc Welding (GTAW)
• Gases for Plasma Arc Welding (PAW)
• Gases for Laser Beam Welding (LBW)
