PROBLEM TO BE SOLVED: To suppress the generation of weld burrs at the time of welding by closely pressing a pressurizing body consisting of an insulating material against the surface of butted place between two steels. SOLUTION: Because the pressurizing face 51 of the pressurizing body 5 consisting of the insulating material is closely pressed against the surface of the butted place between two steels 1, 2, the weld burrs are pressed in with the pressurizing body 5 at the time of welding, weld mark can be smoothed and a finishing stage for removing the burrs after completing welding is unnecessitated. And, the generation of difference in level in the butted place is prevented, the positioning of the steels 1, 2 in the butted place is enabled and fine welding is executed. Furthermore, the pressurizing body 5 consisting of the insulating material may be anything which has heat resistance and strength for pressing the butted place between works to be welded at the time of welding and ceramic, for example, or the like is usable. |
