Title:

LASER WELDING DEVICE

Document Type and Number:

WIPO Patent Application WO/2022/208827

Kind Code:

A1

Abstract:

The present invention reduces retraction of a joining bead surface while also making a weld mark smoother when welding a layered part in which a first workpiece and a second workpiece overlap.　A first trajectory Loc1 for forming a joining bead 18 has an open loop shape in which a start point P1 and an end point P2 are separated. A second trajectory Loc2, Loc3 for forming a non-penetrating bead 20 has a start point P3 inward of the start point P1 of the first trajectory Loc1, extends from the start point P3 along and inward of the first trajectory Loc1, continues to an outer set position P4 which is set outward of and past the first trajectory Loc1 in the vicinity of the end point P2 of the first trajectory Loc1, and thereafter connects to a set point P5 which is an end point set inward of the first trajectory Loc1.
