FIELD: processes and equipment for electric contact welding on with use of wire, possibly for restoring worn parts of machines.
SUBSTANCE: method comprises steps of applying onto surface of welded-on shaft beads of metallic coating partially superimposed one to other along width; plastically deforming additive wire heated by electric current pulses by means of effort of rotating guiding roller being fed along axis of shaft; limiting deformation of additive wire in direction of feeding roller, for example in the form of ring; displacing limitation zone at feeding roller.
EFFECT: enhanced structural uniformity of metallic coating due to increased tempering zone along width of welded-on bead.
