Abstract
A method of plasma surfacing with side feeding of solid and flux-cored wires was improved. A feature of this method is an alternating pulse nature of burning of straight polarity arcs between plasmatron nonconsumable electrode-item and plasmatron nonconsumable electrode-wire that increases surfacing efficiency and decreases base metal penetration depth.
