Abstract:
In a laser welding method, first, laser light is irradiated on one side surface of one of the metal members to form a protruding portion projecting from the other side surface on the opposite side. Next, a part of the protruding portion that was formed is melted by scanning the laser light to generate a metal melt flow toward a top of the protruding portion so as to form a protrusion. The protrusion projects farther from the other side surface than a height of the protruding portion that was initially formed. Then, the one of the metal member having the protrusion is superposed on another of the metal members so that the protrusion is interposed therebetween. Next, the laser light is irradiated onto a portion where the metal members are superposed to weld the metal members to each other.

Claim (Index 1):
A laser welding method for welding a plurality of metal members to each other by irradiating laser light onto a portion where the plurality of metal members have been superposed, in which at least one of the metal members from among the plurality of the metal members is formed from a metal-plated steel plate in which a base metal has been covered with a coating material that has a melting point below that of the base metal, the laser welding method comprising:\n irradiating laser light on one side surface of one of the metal members to form a protruding portion on the other side surface on the opposite side so as to project from the other side surface, and next, melting a part of the protruding portion that was formed by scanning the laser light to generate a metal melt flow toward a top of the protruding portion so as to form a protrusion projecting farther from the other side surface than a height of the protruding portion; and superposing the one of the metal member having the protrusion on another of the metal members so that the protrusion is interposed therebetween, and irradiating the laser light onto a portion where the plurality of metal members are superposed to weld the plurality of metal members to each other.
