Abstract

Spot-welded joints are widely used in industries. A simplified structural model is proposed in this paper to study the residual stresses in spot-welded joints. The current paper describes the influence of the weld parameters on the residual stresses of resistance spot welds on 304 type stainless steel sheets. Various loading conditions and joint parameters are considered. It is found that the increase of both weld current and weld time decreases the residual stresses, and the increase of electrode force decreases the residual stresses. The nugget diameter increases continuously with weld current.

Keywords
