| description | To provide a laser welding method in which a plurality of metal plates including aluminium alloy castings are superimposed and welded, in which a large blow hole is suppressed from being generated in a welded part while suppressing deterioration in productivity.SOLUTION: A laser welding method, in which a plurality of metal plates 10 and 20 including aluminium alloy castings 20 are superimposed and welded by laser beams LB, includes: a melting path in which a first laser beam LB1 is irradiated to a superimposed part 5 having an aluminium alloy plate 10 is superimposed with the aluminium alloy casting 20 while scanning the part to draw a circle to form molten pool 7 having the aluminum alloy plate 10 and the aluminum alloy casting plate 20 melted; and a stirring path in which a second laser beam LB2 is irradiated to the molten pool 7 while scanning the pool at scanning speed Vfaster than scanning speed Vof the laser beam LB1 to draw a circle to stir the molten pool 7.SELECTED DRAWING: Figure 5
【課題】アルミニウム合金鋳物を含む複数の金属板を重ね合せ溶接するレーザ溶接方法において、生産性の低下を抑えつつ、大きなブローホールが溶接部に発生するのを抑える。【解決手段】アルミニウム合金鋳物板２０を含む複数の金属板１０，２０をレーザビームＬＢによって重ね合せ溶接するレーザ溶接方法である。アルミニウム合金板１０とアルミニウム合金鋳物板２０とを重ね合せた重ね合せ部５に対して、第１のレーザビームＬＢ１を、円形を描くように走査しながら照射してアルミニウム合金板１０およびアルミニウム合金鋳物板２０が溶融した溶融池７を形成する溶融パスと、溶融池７に対して、第２のレーザビームＬＢ２を、第１のレーザビームＬＢ１の走査速度Ｖ1よりも速い走査速度Ｖ2で円形を描くように走査しながら照射して溶融池７を攪拌する攪拌パスと、を含む。【選択図】図５ |
