Application Number: JP,2024-113344
Category (FI): B23K26/073,B23K26/21@F,B23K26/067
Stage: PROBLEM TO BE SOLVED: To provide a technique for easily forming a welded member without a hole caused by a gap even when the gap is formed between butted end faces of two metal plates.SOLUTION: In the method for manufacturing a welded member, an irradiation region that is a region irradiated with the laser beam is relatively moved along the end surface. The irradiation region includes a first region, a second region, and a third region. The second region is a region surrounding an outer periphery of the first region. The third area is an area located outside the second area and at least in front of the second area in the moving direction. The movement direction is a direction in which the irradiation region relatively moves. In the moving direction, a rear end of the third region is located on the front side of a rear end of the second region. The power densities q1 of the laser beams with which the first region is irradiated, the power densities q2 of the laser beams with which the second region is irradiated, and the power densities q3 of the laser beams with which the third region is irradiated satisfy a relationship of q1> q2, q3.SELECTED DRAWING: Figure 4 (Grant)
