New approaches to the rational choice of powder filler materials, overlay micro-plasma powder welding process techniques and equipments, heat treatment modes for the restoration of aviation GTE parts from difficult to weld nickel-based superalloys of ZhS32 and ZhS6 types have been proposed and practically tested. The basic principles of reaction-diffusion welding technology were invented and practically tested for heterogeneous nickel-base superalloys joints: cast-deformed alloy (VZhL12U + EI698); cast-overlay metal (ZhS6U + Rene 80).
