Failure mode and strength analyses of resistance spot weld joints of aluminium and austenitic stainless steel sheet

Abstract

Resistance spot welding (RSW) is considered as the dominant process for joining similar and dissimilar sheet metals in automotive industry. In this paper will be present the strength analyses of spot weld joint and analyse the transition between interfacial and pull-out failure modes for resistance spot weld joints of aluminium and austenitic stainless steel sheet, during the tensile–shear test, by usage analytical and experimental approach. For experimental testing, the specimen of 1 mm and 2 mm thickness were used, welded with different welding parameters.
