    Abstract: PROBLEM TO BE SOLVED: To constantly control a clearance of parts to be welded to a minimum by bringing an elastic pressure plate into pressurized contact with outer peripheral face of both plates and irradiating parts to be welded adjacent to the part to be pressurized with a laser beam or an electron beam when coiling a metal flat plate and a metal corrugated plate by a coiling shaft. SOLUTION: By advancing a first and second moving plates 531 , 532 , a first and second pressurizing rollers 541 , 542 are respectively brought into pressurized contact with an outer face of a metal flat plate 2. By manually operating a second laser welding means 56 and by a laser beam irradiated from welding torches 61..., mutually contacted parts of the metal flat plates are subjected to spot welding at an appropriate interval. Further, by sending a metal corrugated plate 3 to a coiling shaft 30, its start end is spot welded to an outer peripheral face of the metal flat plate 2. This welding is conducted by an irradiation laser beam of the manually operated welding torches 61... From a stage that a mountain part of the first pressure roller 54 is engaged with a first valley part of the metal corrugated plate 3, a welding control unit 64 is made in operation.
