Residual stresses at the interface of spot welded dissimilar metals between carbon steel and austenitic steel have been studied. Carbon steel SS400 with thickness of 3.0 mm and 1.0 mm thick austenitic stainless steel SUS304 were joined in a lap joint by resistance spot weld (RSW). Residual stresses at the interface of spot welded similar metals 3.0 mm and 1.0 mm thick austenitic stainless steel SUS304 were also measured as a comparison. Neutron diffraction was used to determine the normal, radial and hoop residual stresses. Residual stresses, both on the side of carbon steel and stainless steel, either the normal, radial and hoop direction tend to compressive and vary depending on the distance from the nugget center. These stresses differ from the residual stresses at the interface of spot welded similar austenitic stainless steel that tend to tensile.
