Shielding Gases for GMA & GTA Welding

Abstract

The function of shielding gases in GTAW (GAS TUNGSTEN ARC WELDING) and GMAW (GAS METAL ARC WELDING) processes and their applications, alongwith brief introduction have been discussed here to enable the user to critically assess the shielding gas requirements for given application and the key areas the emphasis are to be made for higher productivities.
