dc.description.abstractDual-Phase steel has been used in body-in-white in order to reduce the weight and enhance the safety of automobiles. One of the most used technology for joining steel in automotive industry is Resistance spot welding. This paper presnet the analysis of the welding current influence on the microhardness and weld nugget diameter. It will be shown in the paper that the increased hardness of the fusion zones reduces the possibility of the necking in the base metal (i. e. Pull-out Fracture - PF mode), which is not considered as a favorable case.Specimens welded with current of 8 kA showed the best mechanical characteristics, the failure load was approximately 20000 N, the hardness of the fusion zone was approximately 350 HV and during the tensile-shear test they faile in PF mode.
