The utility model relates to the field of laser cladding, in particular to a metal powder laser forming nozzle. Comprising a laser channel and metal powder nozzle insertion cavities formed in the two sides of the laser channel. The outer part of the laser channel is of a cylindrical cavity structure, and a laser nozzle with a conical outer part is arranged below the laser channel; two sides of the laser nozzle are obliquely provided with two metal powder spray head insertion cavities along the laser nozzle; a metal powder spray head can be inserted into each metal powder spray head insertion cavity; the powder spraying path of the metal powder spraying head intersects with the laser spraying path. An annular heat dissipation device installation groove is formed in the inner wall of the laser channel, and the heat absorption end installation groove of the heat dissipation device is inserted into the heat dissipation device installation groove. According to the device, the heat pipe is embedded for heat dissipa
