PROBLEM TO BE SOLVED: To provide a laser welding method that enables a laminate of a plurality of metal plates to be easily and reliably connected together.SOLUTION: In a laser welding method for a metal plate laminate, one of two metal plates overlapping each other is provided with a protrusion; the protrusion abuts on the other metal plate; and a laser beam is applied to the protrusion to melt it, while a force is applied between the two metal plates so that pressure can be applied to this abutting part.

    【課題】複数枚の金属板の積層体を簡単かつ確実に結合させることが可能なレーザ溶接方法を提供する。【解決手段】金属板積層体のレーザ溶接方法において、積層される2つの金属板の一方に突出部を設け、該突出部を他方の金属板に当接させ、該当接部分に圧力が付与されるように2つの金属板の間に力を加えながら、突出部に対してレーザ光を照射して溶融させるようにした。【選択図】図3
