Abstract

PURPOSE: To enable efficient welding without scratches on the product surface by using an electric resistance welding device which heats a V-shape groove of weld material by electric current and presses the groove by a pressing device to make press welding.
CONSTITUTION: When inserting the electrode 13 into the V-shape groove of weld material 9 such as an electric resistance welded pipe, the electrode 13 is held under certain pressure by the butt surfaces 16. By feeding each phase of single phase electric source to each electrode plate 14, electric current runs along the surface of V-shape groove near the butt surfaces 16, and the butt surfaces 16 are directly heated. Thus, the welding material 9 is press welded by pressing devices 11 while the material is fed by the feeder.
