<p><P>PROBLEM TO BE SOLVED: To provide a laser beam welding method by which a necessary gap is surely formed between overlapped members to be welded. <P>SOLUTION: In a method for welding by forming a weld bead 7 with the laser 5 after forming the gap 11 between the members 1, 2 by warping a member 1 on one side by forming a forming bead 6 with the laser 5 when welding the overlapped members 1, 2 by a laser 5, the forming bead 6 is formed into a nonlinear shape. The forming bead 6 may be also made in non-parallel to the weld bead 7. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
