Summary: | The invention relates to the technical field of laser cladding welding, in particular to an underwater local dry laser cladding nozzle. The nozzle comprises a nozzle body and a connecting base in threaded connection with the top of the nozzle body, a circle of flange is annularly arranged at an inlet of the top of the nozzle body, a clamping groove clamped to the flange is formed in the bottom of the connecting base, and protective glass abutting against the flange is arranged in the clamping groove of the connecting base. A plurality of shielding gas channels are evenly arranged in the side wall of the nozzle body at intervals in the circumferential direction of the nozzle body. The device is reasonable in structural design and convenient to operate, a nozzle based on the Venturi principle is adopted at the tail end of a drainage channel, a stable and efficient drainage air curtain can be formed, diffusion of air in a cladding area is facilitated, a stable water-free cladding area environment is formed, and |
