Abstract
A welding method includes: forming a workpiece by stacking plated sheet members having a plating layer formed on a surface of a base material; disposing the workpiece in an area to be irradiated with laser light; irradiating a surface of the workpiece with a plurality of beams by dispersing positions such that centers of the beams do not overlap with each other within a prescribed area on the surface; while continuing the irradiation, relatively moving the beams and the workpiece and sweeping the beams on the workpiece so as to melt an irradiated part of the workpiece for performing welding; and setting a distance between the beams to be emitted such that weld pools formed in the workpiece by irradiation of each of the beams overlap with each other.
