Abstract
A method of resistance-welding two laminates each having a basic structure of a metal layer/a thermally softenable insulating layer/a metal layer, which allows welding with excellent welding strength and good outer appearance of a welded spot. In this method, two laminates are prepared in which each metal layer has a thickness of 0.02 to 0.5 mm, and a ratio of the total thickness of the metal layers of each laminate to the thickness of the laminate falls within a range between 1/3 and 2/3. Electrodes held at a temperature above the softening temperature of the insulating layers are urged against the laminates to soften the insulating layers and so bring the metal layers into contact with each other and to resistance-weld the laminates.
