PURPOSE:To simplify the removing work of a scrap and to execute it as a continued work in a series of welding works, by removing a scrap by the advance of a metallic strip. CONSTITUTION:Opposed end parts 1a, 2a of a preceding plate 1 and a following plate 2 are superposed on lower clamp bases 8, 9 of the preceding side and the following side, and thereafter, clamps 3, 4 descend and clamp said parts. Subsequently, a rotary wheel cutting body 6 is made to descend, run in a plate width direction and cuts the plate. After cutting, both the preceding and the following clamps 3, 4 are made to ascend, the preceding plate 1 is advanced to a downstream side by a pair of moving clamps 5, and at the same time, the scrap 1b of the following plate placed on is also moved and removed. On the other hand, the following plate 2 is moved backward a little to an upstream side, and thereafter, advanced to the downstream side, and the scrap 2b of the preceding plate 1 is removed. After the scrap has been removed, a cutting plane of the following plate 2 is butted to the cutting plane of the preceding plate 1, a laser welding torch is run along the same passage as the running passage of the rotary wheel cutting body 6, and a laser welding is executed satisfactorily. |
