发明名称 Laser welding method and laser welding apparatus
摘要 A laser welding apparatus includes laser generator, arc generator, wire feeder, filler feeder, filler-feeding-abnormality detector, and controller. Controller stops welding immediately upon receiving a filler-feeding-abnormality signal from filler-feeding-abnormality detector. This can stop welding before the formation of a defective weld bead, and can also prevent the breakage of the welding apparatus.

主权项 1. A method for laser welding in which a filler is fed to a welding position of an object to be welded while a laser beam is applied to the welding position, the method comprising: a detecting step to detect an abnormality in feeding of the filler; and a filler-feed stopping step to stop the feeding of the filler immediately after the detecting step.
