Abstract: Aluminium alloy and austenitic stainless steel were welded using a thermal compensation resistance spot welding technology. The interface region was observed using electron microscopy, and the temperature distribution on the welding zone was investigated as well. The results reveal that higher heat can be obtained in thermal compensation resistance spot welding in comparison with conventional one, and that the morphology and thickness of the reaction layer vary with the position at the welding interface.

Keywords: aluminium alloys; stainless steel; interface region; microstructure; thermal compensation resistance spot welding; welded joints; temperature distribution; welding interface.
