Abstract
PURPOSE:To make it possible to resistance-spot-weld with good workability even when the electric resistances of metal skin materials, which are laminated to both sides of a resin plate, are different from each other by a method wherein metallic deposits, the electric resistance of each of which is higher than that of the metal skin material, are formed on the surfaces, which abut against the resin plate, of the metal skin materials of a laminated metal sheet. CONSTITUTION:Metallic deposits 6a and 6b, the electric resistances of which are at least higher than that of metal skin materials 1b and 1c made of cold-rolled steel plate, such as chromium, lead or the like are formed on the surfaces, which abut against a resin plate 1a, of the metal skin materials 1b and 1c. Since the generation of heat becomes larger in the vicinities of the metallic deposits 6a and 6b having higher electric resistances during the joining of the laminated metal sheet 1 to a plain carbon steel plate 2 by spot welding, a nugget 7 is surely formed between the metal skin materials 1b and 1c during the resistance welding of the laminated metal sheet 1 and the plain carbon steel plate. Further, the nugget can surely be formed, even when the difference between the electric resistances of the metal skin materials 1b and 1c presents, resulting in making the consideration of the side of the laminated metal sheet 1 unnecessary and accordingly improving its workability.
