Effect of pulsed current on temperature distribution, weld bead profiles and characteristics of gas tungsten arc welded aluminum alloy joints
TL;DR: In this article, the effects of pulsed current welding on tensile properties, hardness profiles, microstructural features and residual stress distribution of aluminium alloy joints were reported, and it was found to improve the tensile property of the weld compared with continuous current welding due to grain refinement occurring in the fusion zone.
