摘要： An object of the present invention is to provide a powder supply nozzle and an overlaying method which make it possible to restrain oxidation of a clad layer part and to produce a clad layer part with high quality. The invention provides a powder supply nozzle including: a laser emission part for irradiating a workpiece with a laser beam; and a powder supply part disposed in the periphery of the laser emission part and adapted to discharge a powder onto a laser-irradiated part, wherein a mechanism for guiding the air surrounding the laser-irradiated part to the exterior of the laser-irradiated part is provided in the periphery of the powder supply part.
