レーザ溶接装置およびレーザ溶接方法

Japanese Patent JP4107639

B2

In order to implement lamination welding in which there is little distortion and the bonding strength is high by means of laser beam, a laser welding device comprises: a first laser beam emitting head directed to a layered base material composed of two or more layers in a superimposed direction; a first skirting roller rotatably supported by means of a first supporting member on which the first laser beam emitting head is fixed and provided with a peripheral surface which protrudes more at a base material side than a base material opposing end of the first laser beam emitting head; a second laser beam emitting head directed to the layered base material from the opposite side of the first laser beam emitting head in the superimposed direction; a second skirting roller rotatably supported by means of a second supporting member 14 on which the second laser beam emitting head is fixed and provided with a peripheral surface which protrudes more at a base material side than a base material opposing end of the second laser beam emitting head; and a first pressing means for pressing the first supporting member with respect to a supporting base holder in the superimposed direction.
