PURPOSE: To make a cutting line and a weld line coincide with each other by crossing a preceding plate and a following plate in a carrying direction, running a rotary wheel cutting body and cutting them separately, and on the other hand, running a welding torch along a running locus of this cutting body.
CONSTITUTION: The rear end part 1' of a preceding plate 1 is fixed by a preceding clamp 13, a following clamp 14 and a moving clamp 33, and the rear end part 1' is cut by running the rotary wheel cutting body 19 in the plate width direction. By the moving clamp 33, the preceding plate 1 is advanced by a prescribed distance (l) to a downstream side, and a scrap 1a is swept down by advancing a following plate 2. Next, a tip part 2' is fixed by the preceding clamp 13 and the following clamp 14, and thereafter, it is cut by the cutting body 19. Thereafter, the following plate 2 is advanced, and the scrap of the following plate is swept down. Next, the preceding plate 2 is moved backward to its original position by the moving clamp 33, and the cutting plane of the preceding plate 2 is made to coincide with the running locus of the cutting body 19 and fixed by the clamp 13. Thereafter, the cutting plane of the following plate 2 is butted to the cutting plane of the preceding plate 2, fixed by the following clamp 14, and welding is executed by running a welding torch along the running locus of the cutting body 19.
