Abstract

We develop a coaxial multilayer solid wire to use in Gas Metal Arc welding with pure Ar shielding gas (Ar-GMA welding). The oxygen concentration in weld metal that degrades the welded parts is reduced using by Ar-GMA welding. We produce stable welds with pure Ar shielding gas and obtain a high-quality joint with improved toughness.
