Zusammenfassung:	PROBLEM TO BE SOLVED: To stably feed a wire to a weld zone.SOLUTION: A laser welding apparatus includes a wire feeding device that feeds a wire 4 to a material 1 to be welded, and a laser head that generates a first laser beam for being applied to the material 1 to be welded and a second laser beam 3 for being applied to the wire. In the laser welding apparatus, a molten pool is formed by applying the first laser beam to the material to be welded, and the second laser beam is applied at a temperature lower than a melting point of the wire to the wire fed to the molten pool.
