FIELD: process engineering.
SUBSTANCE: proposed method may be used for reconditioning worn-out parts by electric contact welding of metal wires. Prior to welding bundle of metal wires differing in properties is formed. Note here that said wires are braided in, at least, two layers with opposite direction of twisting. Formed bundle is pressed against to part surface to be built up by electrode roller and welded thereto by electric current pulses between electrode roller, bundle of wires and part. Increased heat release and low stiffness of bundle facilitate heating and deformation of filler as well as production of strong weld seam.
EFFECT: coating with required set of mechanical properties.
