FIELD: processes for electric - resistance roller welding-on of metallic powder materials at restoring worn and working surfaces of parts such as bodies of revolution.
SUBSTANCE: method comprises steps of forming belt of metallic powder, binder material and metallic gauze by feeding them to inter-roll gap and rolling between heated rolls; feeding belt to welding-on zone roller electrode-part; rotating part at welding -on rate, simultaneously passing welding current pulses and providing continuous motion of roller electrode along part axis. Revolution number of heated rolls coincides with revolution number of part.
EFFECT: improved quality of applied coating layer, enlarged assortment of powder material types.
