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.
