FIELD: process engineering.
SUBSTANCE: invention relates to parts reconditioning by buildup under welding compound layer. Buildup head comprises mechanisms to feed main and filler wires, current conducting element with main wire feed channel, nozzle to feed filler wire there through for doping of buildup layer. Jet and adjustment mechanism with adjustment screw are arranged at current conducting element case. Case of said adjustment mechanism contacts via insulator with filler wire feed nozzle. Extra spherical insulator is secured at nozzle end. Extra filler wire nozzle is secured on both or one side from current conducting element. Extra filler wire nozzle and current conducting element are located in one plane perpendicular to machined part rotary axis.
EFFECT: high-quality of buildup layer of preset composition and metal properties.
