Abstract
The influence of a hollow non-consumable electrode arc in surfacing by the plasma-MIG process on the mode of melting of flux-cored wire axially fed through the plasmatron channel, is determined. Its positive effect on the uniformity of melting of the wire core and metal sheath is established. It is shown that surfacing by plasma-MIG process can be performed at a lower current of the consumable electrode without short-circuiting of the arc gap and with minimal penetration of the base metal
Keywords: plasma surfacing, surfacing modes, electrode melting, metal transfer, flux-cored wire
