摘要：
A thermomechanical finite element (FE) model was used to examine the effects of resistance spot welding (RSW) current intensity, time, and electrode force on the distribution of temperatures and the size of nuggets of IN-625 superalloy sheets. In order to evaluate and optimize the mechanical properties of RSW welded IN-625 alloy, a procedure was developed based on simulation results. A taguchi L9 experimental design was used to study the mechanical properties of welded samples as a function of peak load, failure mode, and energy. According to the findings, joint fracture modes and strength are significantly influenced by process parameters. Consequently, welding current, electrode force, and welding time all had significant impacts on the shear strength of IN-625 Alloy spot welding joints, with impacts of 62.05%, 24.06%, and 12.84%, respectively.
