Abstract:
A hybrid welding apparatus, comprising:a laser generator for emitting a laser beam;a condenser optical system including lenses each having a hole portion in the center such that the laser beam from the laser generator is condensed by the lenses to subject a base metal to laser welding;a supply holder passed through the respective hole portions of said lenses, whereby a welding wire is supplied substantially coaxially with the axis of said lenses, said supply holder including a tube through which said welding wire is passed and a coolant passage for circulating coolant therein; andan arc welding power source for supplying current to said welding wire and said base metal, thereby subjecting the same portion of the base metal that is subjected to laser welding with gas-shielded arc welding;wherein said condenser optical system is overlain by a reflector for deflecting said laser beam in the direction of the axis of said condenser optical system, said supply holder penetrating said reflector.
