Abstract
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.
