Abstract
A laser welding device for executing stable, highly reliable edge joint welding by laser beam comprises: a laser beam emitting head directed to a layered bonding position on an end surface in an edge of a layered base material; a first set of rollers for being along one plane of the base material; a second set of rollers for being along the other plane opposing the plane; a first member which rotatably supports the rollers and which is coupled with the head; a second member which rotatably supports the rollers and which is coupled with the head; and a pressing means for driving at least one of the first and second members and in a direction in which the gap between the rollers and the rollers is reduced in order to sandwich and press the base material by means of the rollers.
