Method of resistance-welding workpieces of metal and resistance-welded weldment of metal

摘要

Workpieces of aluminum alloy are resistance-welded while a powdery mixture of magnesium and a metal oxide is being interposed between regions of workpieces of aluminum alloy which are to be joined to each other. The metal oxide may comprise at least one material selected from the group consisting of TiO2, SiO2, Cr2O3, MnO2, Fe2O3, CuO, and Ti2O3 and the powdery mixture may include aluminum powder. The workpieces may be made of aluminum, stainless steel, or the like rather than aluminum alloy.
