    • A laser welding method includes emitting two laser beams along a weld line from an upper surface side of a workpiece, the two laser beams being transmitted through different optical fibers and having in-focus spot diameters of 0.3 mm or larger; emitting the laser beams such that a leading laser beam of the two laser beams and a trailing laser beam of the two laser beams are each inclined toward a direction in which welding proceeds at an incident angle with respect to a direction perpendicular to an upper surface of the workpiece, the leading laser beam being ahead of the trailing laser beam on the upper surface of the workpiece in the direction in which welding proceeds, the trailing laser beam being behind the leading laser beam; and setting the incident angle of the leading laser beam to be larger than the incident angle of the trailing laser beam.
    • 激光焊接方法包括沿着焊接线从工件的上表面侧发射两束激光束,两束激光束透过不同的光纤并具有0.3mm以上的焦点直径; 发射激光束,使得两个激光束的前导激光束和两个激光束的后退激光束各自朝着焊接相对于垂直于上表面的方向以入射角进行的方向倾斜 所述工件,所述前导激光束在所述工件的上表面上在所述焊接进行方向上位于所述尾部激光束之前,所述后激光束位于所述激光束的后面; 并且将前导激光束的入射角设定为大于后激光束的入射角。
