A powder material for use in resistance welding articles of aluminum comprises a mixture of 10-50% by weight of a liquid resin and the remaining proportion of a magnesium powder or a blend of magnesium and aluminum powders. Also a method of resistance welding articles of aluminum comprises the steps of preparing a pasty mixture by mixing in a predetermined amount of a liquid resin having a predetermined initial viscosity, a predetermined amount of a metal powder or a blend of metal and metal oxide powders, and inserting the pasty mixture between the mating weld surfaces of the aluminum articles. Only a small welding force and a low current will be required in producing a resistance weld connection between the aluminum articles with desired strength.

An aluminum weldment is produced by resistance-welding aluminum workpieces, and has a nugget formed between the aluminum workpieces which contains more magnesium than the base material of the aluminum workpieces. The nugget contains 5.about.17 wt % of magnesium which forms a solid solution with aluminum.

Aluminum weldment and method of welding aluminum workpieces

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 TiO.sub.2, SiO.sub.2, Cr.sub.2 O.sub.3, MnO.sub.2, Fe.sub.2 O.sub.3, CuO, and Ti.sub.2 O.sub.3 and the powdery mixture may include aluminum powder. The workpieces may be made of aluminum, stainless steel, or the like rather than aluminum alloy.
