A domestic plant for additive techniques of different materials fritting is presented. The plant in its basis has a high-powered (up to 2.5 kW) waveguide CO2 – laser possessing a unique in the uniformity of emission power density distribution on a target. The results of nickel-based heat-resistant alloy fritting of TCNA-1VR, VZhL12U and VZh159 types developed for manufacturing complex contoured parts of gas turbine engines (GTE) by a method of layered laser alloying and for complex contoured parts GTE repair by a method of gas powder laser surfacing are shown. During laser remelting of these powders it is possible to grow a billet with a homogeneous fine-grain structure which manufacturing is impossible at common techniques of casting.
