Abstract

Provided is a butt laser-welding method for a metallic member in which a laser beam (LB) is scanned so as to repeatedly cross butting surfaces of metallic members (10, 20) to weld the metallic members (10, 20) to each other. When the laser beam (LB) is scanned so as to cross the butting surfaces, the closer the laser beam (LB) comes to the butting surfaces, the more an irradiation energy density of the laser beam (LB) is increased. The bottom surfaces (B1, B2) of the molten pools formed on the metallic members (10, 20) are inclined so as to descend toward the butting surfaces.
