FIELD: processes for surfacing with use of lying electrode, possibly restoration of worn surfaces of parts in different industry branches.
SUBSTANCE: method for surfacing bead of rollers of road building machines comprises steps of arranging roller in such a way that its axis is vertical; dividing surfaced zone of bead by technological sectors; forming electrodes of n mutually joined rods bent along arcs of sectors and arranging them on surfaced area of respective sector with gap; supplying flux and additive powder material to surfaced zone; connecting electrode and part with power source for exciting electric arc and performing surfacing; placing electrodes on sectors of bead simultaneously along the whole circle; electrically connecting front end of one electrode with bead; at surfacing narrow beads, forming electrodes of n mutually joined rods arranged one over another.
EFFECT: enlarged manufacturing possibilities of method for surfacing parts with annular worn surface, lowered cost, enhanced efficiency of process.
