摘要：

Improving weld quality, enhancing weldment properties, and reducing failure rates were the primary objectives of this research. To achieve the above characteristics, a simulation was conducted for dissimilar welding of IN625 and SS316L using an autogenous approach. ANSYS software was utilized to forecast temperature distribution, weld pool characteristics, and residual stress (RS) measurements post-simulation. The dissimilar metals were welded via autogenous TIG process, with cross-section weldments revealing the macrostructure of the weld pool. RS measurement was carried out using the Debye-Scherrer (DS) rings method. Simulation played a crucial role in minimizing weldment failure rates. The DS ring analysis pinpointed the maximum tensile residual stress (TRS) at 178 MPa within the fusion zone (FZ).Graphical AbstractFE thermo-mechanical simulation of Dissimilar welding and residual stresses
