ABSTRACT:
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.
