激光焊接方法
摘要：
本发明提供一种激光焊接方法，根据本发明的激光焊接方法用于通过在使扫描激光束(16)的扫描单元(11)移动的同时将由扫描单元扫描的激光束(16)施加至多个金属板(31)和(32)来焊接该多个金属板(31)和(32)，所述激光焊接方法包括：在使扫描单元移动的同时在扫描单元的扫描范围内对待焊接物体的在焊接方向上的预定部位执行预固定焊接的步骤和对所述待焊接物体的与预固定过的部位对应的部位执行主焊接的步骤。此外，当对待焊接物体的与预固定过的部位对应的所述部位进行主焊接时，可以在待主焊接的部位的两侧都受约束的情况下对所述部位进行主焊接。
摘要（英）：

The invention provides a laser welding method. The laser welding method according to the invention is used for welding a plurality of metal plates (31) and (32) by applying a laser beam (16) scanned by a scanning unit to the plurality of metal plates (31) and (32) while moving the scanning unit (11) scanning the laser beam (16). The laser welding method includes the steps of: performing a step of preliminary-fixation-welding on a predetermined place in a welding direction of an object to be welded, and a step of main-welding on a place corresponding to the preliminarily-fixed place of the object to be welded within a scanning range of the scanning unit while moving the scanning unit. Further, when the place corresponding to the preliminarily-fixed place of the object to be welded is main-welded, the place is main-welded in a state where both sides of the place to be main-welded are restrained.
