Estimating the term…
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.
A material for use in resistance welding articles of aluminum, comprising a spreadable pasty mixture of 10-50% by weight of a liquid resin, 2-65% by weight of a metal oxide powder and the remaining proportion of at least one of either an aluminum powder or a magnesium powder, or both;
A method of resistance welding articles of aluminum, comprising the steps of preparing a pasty mixture by adding a liquid resin to a blend of a metal oxide powder with at least one of either an aluminum powder or a magnesium powder, or both, and inserting said pasty mixture between the mating weld surfaces of said aluminum articles.
A method of resistance welding articles of aluminum, comprising the steps of preparing a pasty mixture by mixing 10-50% by weight of a liquid resin having an initial viscosity larger than 0.1 Pa.s and smaller than 80 Pa.s, with the remaining proportion of a metal powder and 2-65% by weight of a metal oxide powder, inserting said pasty mixture between the mating weld surfaces of said aluminum articles, and causing said pasty mixture to spread over the mating weld surfaces by imparting a pressure on said pasty mixture, through said aluminum articles, by welding electrodes engaging said aluminum articles at the time of the resistance welding.
