Abstract

This paper presents an experimental study on the fracture toughness in similar and dissimilar of resistance spot welded dual phase and ferritic stainless steel sheets. The sheet materials were joined by using resistance spot welding as a lap joint. Tensile-shear tests were applied to the welded specimens. The variation of the Nugget diameter according to welding current was investigated. Also, the microhardness distribution was investigated. The results were discussed and plotted as graphs.
