溶接用プラズマトーチ。[Scope of Claim for Utility Model Registration] (1) A supply nozzle having a carrier gas supply path for overlay powder and the same powder is provided surrounding a central nozzle having an electrode rod for plasma arc, and surrounding the supply nozzle. A shield cap having a shield gas ejection nozzle is provided in the shield cap, and the plasma arc and the supplied powder are enclosed within the shield cap through a partition wall that vertically divides the annular cylindrical space inside the cap into an inner and outer space. A plasma torch for powder overlay welding, characterized in that an inner shielding gas nozzle for ejecting a shielding gas flow and an outer shielding gas nozzle for ejecting a shielding gas surrounding the ejected gas flow from the inner shielding gas nozzle are arranged in parallel. . (2) The gas outlet of the outer shield gas nozzle is narrower than the gas outlet of the inner gas shield nozzle, and the width t of the outlet is t/D = 3/100 or less of the shield diameter D of the shield cap. A plasma torch for powder overlay welding according to claim 1 of the utility model registration claim.
