Abstract
The invention discloses a coaxial nozzle. The coaxial nozzle comprises a nozzle shell, a laser groove, protective gas pipelines, a powder groove and powder pipelines. The laser groove which vertically penetrates through the nozzle shell is arranged on the laser shell, wherein the nozzle shell and the laser groove are coaxially arranged. The protective gas pipelines horizontally penetrate into the laser groove from the two sides of the nozzle shell respectively. The powder groove surrounds the laser groove. The powder groove is of a cone structure, wherein the bottom end of the cone is open. The powder pipelines horizontally penetrate into the powder groove from the two sides of the nozzle shell and are used for conveying powder. The coaxial nozzle is suitable for the laser cladding technology. By the adoption of the coaxial nozzle, accurate cladding can be conducted, efficient locating of powder can be achieved, powder flow can evenly surround a laser beam, the direction does not need to be considered when the coaxial nozzle is used, and the excellent cladding quality can be obtained.
