Abstract
A laser welding method of the present disclosure includes a first step and a second step. In the first step, a first end of a first workpiece is positioned such that the first end of the first workpiece is overlapped on a second end of a second workpiece to form a corner joint. In the second step, the first end forming the corner joint is irradiated from above with a laser beam. Additionally, the first end is positioned to protrude relative to the second workpiece in the first step.
