Abstract
PURPOSE: To perform spot welding of Al alloys with a general spot welding machine of single phase AC by interposing straps of a metallic material of lower heat conductivity and electric conductivity than tnose of materials to be welded and a higher m.p. temp. between electrodes and the materials to be welded.
CONSTITUTION: When materials 2a, 2b to be welded which are Al alloy plates are grasped by an upper electrode 1a and a lower electrode 1b via straps 4a, 4b under pressure and are electrically conducted under the same conditions as spot welding conditions for mild steel, a molten part (nugget) 5 of an hourglass shape is formed. A metallic material of heat conductivity and electric conductivity lower than those of the materials 2a, 2b, and a higher m.p. temp., for example, a mild steel plate, an alloy steel plate such as stainless steel plate, a high carbon steel plate or the like is used for the straps 4a, 4b. Thereby, the spot welding of Al alloys is easily accomplished under the welding conditions (low electric current) similar to those in the case of spot welding of mild steel plates, by using an ordinary portable spot welding machine.
