The present study reports the effects of RSW process parameters like heating cycle, welding current and electrode tip diameter on the tensile shear strength and nugget size of dissimilar metal welding of 2205 duplex stainless steel (DSS) and AISI-316L stainless steel sheets. Tensile shear tests were conducted to access the tensile shear strength and associated physical variations of the nugget formed. Finite element (FE) simulation of the tensile–shear test was performed using ABAQUS explicit FE software. The finite element results were compared with experimental results through the aid of graphical representation by com-paring the obtained stress–strain values for validation. The resistance spot welds are subjected to Vickers microhardness test and identified that hardness of HAZ is less for AISI-316L and high in DSS-2205 as compared to respective base metal, moreover heteroge- neous hardness values obtained in the weld metal zone (WMZ) exhibits higher hardness in ASS-316L and low hardness in DSS-2205 side as compared with base metal. Furthermore, SEM fractography indicates that the failure of tensile shear spot welded specimen occurs in the ductile mode of fracture.
