摘要：Gas Tungsten Arc Welding is most commonly called Tungsten Inert Gas welding .TIG welding has become indispensible as a tool for many industries because of the high quality welds produced at relatively low equipment cost. Aluminum Alloy 6082 [AA 6082] is t ypically used in highly stressed applications, trusses, bridges, cranes, trusses, milk churns, transport applications etc. Aluminum Alloy 5083 [AA 5083] is commo nly used in the manufacturing of pressure vessels, marine vessels, storage tanks shipbuilding, armored vehicles, aircraft cryogenics, drilling rigs, structures and even in missile co mponents etc. In this research, AA5083 and AA6082 welds are made with gas tungsten arc welding (GTAW) using AA 5356filler wire with non -pulsed current and pulsed current at different pulse frequencies like 2 pulses/sec, 4 pulses/sec, and 6 pulses/sec using precision TIG 375 welding machine. This report to investigates the weld quality through non destructive testing(NDT) to study the porosity and surface cracks and also the mechanical properties like ultimate tensile strength(UTS), 0.2% yield strength(YS) and % of elongatio n using GTAW with non-pulsed current and pulsed current at different pulse frequencies were studied and also to find the weld joint efficiency o f the weld ments.
