Abstract

PURPOSE:To make laser welding easy, by utilizing a dummy plate which is excellent in cutting characteristic, and making a plate butting surface which becomes a weld line coincide with a laser scanning line easily, in case of butt-welding of a material which is inferior in laser cutting characteristic. CONSTITUTION:A preceding plate 3 of materials 3, 4 to be welded is made to pass through a laser welding and cutting device 2, is stopped, subsequently a dummy plate 12 is forwarded to a prescribed position of said device 2, and it is fused into two pieces 12a, 12b by a laser torch 7. 12a is removed, the cut surface of 12b is left on the running line of the laser torch 7, and after that, the preceding plate 3 is moved backward, and its rear end is butted against the cut surface of 12b and is clamped. 12b is removed, the following material to be welded 4 is forwarded to the laser welding and cutting device 2, and its front end is pressed against the rear end of the preceding plate 3 which has been fixed on the laser torch running line, which is made to a weld line. After the running line center of the laser torch has been aligned exactly with the weld line, the material to be welded 3, 4 are welded by the laser torch 7.
