Title:
HYBRID WELDING METHOD
Document Type and Number:
WIPO Patent Application WO/2024/014292
Kind Code:
A1
Abstract:
A hybrid welding method of the present disclosure comprises a first step for irradiating a surface of a workpiece 40 with laser light LB along a predetermined welding line, and a second step after the first step for further arc-welding the location irradiated with the laser light LB. In the first step, the workpiece 40 is irradiated while scanning the laser light LB two-dimensionally so that a molten pool 41 having a predetermined width in a direction intersecting both the thickness direction of the workpiece 40 and the direction along the welding line is formed. In the second step, the arc welding is performed while repeating positive feeding and reverse feeding of a welding wire 22 at predetermined periods.
