Abstract: PURPOSE:To subject materials to be welded to laser beam spot welding by simple operation by fixing the materials to be welded mutually by restraint from only one side. CONSTITUTION:An annular magnet 14 is arranged on one surface of the materials S1 and S2 to be welded superposed on each other and the materials S1 and S2 to be welded are restrained mutually by the magnetic force of the annular magnet 14. A laser beam head 12 is provided above the annular magnet 14 and a laser beam 13 is emitted to the surface of the material S1 to be welded via a central opening of the annular magnet 14 from the laser beam head 12. When the nonmagnetic materials S1 and S2 are welded together, a ferromagnetic annular metal plate is applied on the rear side and the materials S1 and S2 to be welded are held between the annular metal plate and the annular magnet 14. Accordingly, since the magnetic attraction force by the annular magnet 14 works equally around a weld zone, the materials to be welded are restrained satisfactorily and easily with a welding point as a center.
