METHOD OF HYBRID WELDING AND HYBRID WELDING APPARATUS

摘要

There are provided a laser diode, an irradiating section that applies an output from the laser diode to a base material in the form of a laser beam and thus melts the surface of the base material while moving the laser beam; a wire feeding section that continuously feeds welding wire to a melted portion of the surface of the base material moving along with the movement of the laser beam emitted from the irradiating section; and a wire heating power source that electrifies the welding wire so that the welding wire located in the melted portion of the base material surface is almost melted. In the case of thick plate welding, it is possible to improve operating efficiency and working accuracy, and in the case of welding a hard-to-weld material such as a high-tensile steel board, it is possible to perform welding while preventing deterioration and fracture of metal structure from occurring.
