Abstract

Metal Active Gas (MAG) welding has high quality for joining two or more materials efficiently. 5083 Al grade is selected on the basis of important factors such as corrosion resistance, fabrication, heat treating good combination of toughness and formability. MAG is efficient welding utilized in aerospace, ship & marine industries. Determine the gas flow rate influence on impact strength of 5083 Al-alloy joints with size of 45 mm x 10 mm x 4 mm. In this, maximum impact strength of 17.1 Joule obtained at shielding gas flow of 7 Lt/min with constant current 235 amps.

Keywords- 5083 Al- alloy, Impact strength, Inert gas, MAG welding set up
