Abstract

This paper describes the single-sided resistance spot welding (SSSW) process which is expected to be a productive welding technology for joining stamped sheet panels to hollow parts for auto bodies. To obtain guidelines for making a good weld with SSSW process, the influence of welding parameters and set-up conditions of the specimen upon nugget growth were investigated experimentally. In addition, a numerical study was carried out to establish the mechanism of nugget growth in the SSSW process. Since deflection of parts during welding is one of the features of the SSSW process, this report focuses on the influence of electrode force and the stiffness of the specimen upon nugget formation. In addition, the effect of electrode geometry was examined.
