Popis:	In this study, the effect of welding time on joining capability of austenitic stainless steel (AISI 304) sheets and ferritic stainless steel (AISI 430) sheets by using resistance spot welding (RSW) process was investigated. Therefore, macrostructure, microstructure, microhardness, tensile shear strength, and failure mode of welded materials were determined for various welding times. The welding times values used in the resistance spot welding process were 0.4, 0.8, 1.2, and 1.6 s. Tensile shear tests carried out on the welded joints determined their strength and failure mode. The increase in the welding time resulted in an increase in the nugget size and the weld strength. Two distinct failure modes were observed during the tensile shear test: interfacial, pullout failure modes. Finally, an optimum welding time was obtained.
