FIELD: restoration of worn parts or hardening new ones by means of electric arc surfacing.
SUBSTANCE: method comprises steps of welding-on single bead onto the whole surface of part to be surfaced by means of continuous electric arc; using bead having two annular portions and at least one helical portion; at first surfacing first annular portion, then helical portion and second annular portion; surfacing annular portions of bead in such a way that to place them partially on ends of part along its whole perimeter; after termination of surfacing procedure removing coating from part ends by mechanic working.
EFFECT: enhanced quality of surfaced coating, lowered labor consumption of process.
