Abstract

Gas tungsten arc welding (GTAW) is an electric arc welding process that produces an arc between a nonconsumable electrode and the work to be welded. This paper details the study of the mechanical properties of the weldments of Aluminum Alloy during Gas Tungsten Arc Welding(GTAW) process with Non-Pulsed and Pulsed Current Welding at different frequencies. During this process voltage, gas flow rate and weld speed are kept constant. The weld beads were given post weld heat treatment. The mechanical properties like Tensile Strength, % Elongation, 0.2% Yield Strength of Aluminum Alloy have been studied. The main objectives of the work are to study the effects of filler materials and welding current, penetration of weld beads, tensile properties and the microstructural characteristics of weld beads. Non-destructive and Destructive tests have been conducted on the weldments of Aluminum Alloy. These results have been compared with other specimens, which are welded at Non-pulsed and at different pulsed current welding. To improve the mechanical integrity of the weldments, the Microstructures of the weld Fusion zone (FZ) and Heat Affected Zone (HAZ) are studied and are compared at various currents.
