Trends and new applications of spot welding for aluminium alloy sheets

Interfacial microstructure and strength of steel/aluminum alloy joints welded by resistance spot welding with cover plate

“…However, the utilization of the welding process is still restricted by the aluminum clad steel sheet's high cost and manufacturing difficultness. Therefore, Satonaka et al (2006) developed a new method termed RSW with cover plate for joining between aluminum alloy and steel, and clarified the influence of cover plate on the weld temperature distribution by finite element analyses, in which 200-300 • C higher temperature is obtained than in the weld without use of cover plate. In the present study, we joined aluminum alloy to steels using this technique, investigated the interfacial microstructure and tensile shear strength of joints, and analyzed the effect of reaction layer on the tensile shear strength of joints.…”

“…The by Sotonaka et al 14) . It should be taken into consideration that the cover plates must have lower electrical conductivity compare to aluminium alloy, so that generated heat can be conducted into aluminium alloy from cover plate.…”
