Modeling of heat transfer and fluid flow during gas tungsten arc spot welding of low carbon steel
TL;DR: In this article, the evolution of temperature and velocity fields during gas tungsten arc spot welding of AISI 1005 steel was studied using a transient numerical model and the calculated geometry of the weld fusion zone and heat affected zone and the weld thermal cycles were in good agreement with the corresponding experimental results.

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.
