The present of work is aimed at the TIG process parameters selection and optimization with focus on weld sample output quality parameters namely temperature distribution, residual stresses, weld distortion. A 10 mm thick SS 316 plate of dimensions 300x150mm with TIG welding is selected as experimental investigation and four specimens with thicknesses 20, 15, 10, and 5 mm are taken for FEM analysis using ANSYS software to predict the temperature variation and thermal stresses. Also 4 different materials are included in this study to figure out the thermal stresses post welding in the specimens using simulation. For calculating the thermal stresses coupled field analysis is used, firstly transient thermal analysis is performed and the results are taken as inputs for the structural analysis.
