<P>PROBLEM TO BE SOLVED: To provide a laser jointing method that joints two materials while imparting a sufficient strength thereto and minimizing heat influence. <P>SOLUTION: The method overlaps first and second materials (V1, V2) on each other and irradiates the surface of the first material (V1) with a laser light (103) from the side of the first material (V1). When jointing both materials (V1, V2), the method intermittently irradiating an overlapped part of the first and second materials (V1, V2) with the laser light while moving the laser light (103) to form a welding bead (1) on the surface of the first material (V1), wherein the length of the welding bead (1) is formed gradually shorter. <P>COPYRIGHT: (C)2012,JPO&INPIT |
