Experience in the Use of a Flux Cored Wire as a Filler Wire in the Deposition of Wear-Resistant Coatings

The application of a filler wire in the traditional process of arc surfacing with a flux cored wire in the environment of protective gases is proposed. A flux cored wire of the electrode wire composition is shown to be used as a filler wire. The optimum surfacing parameters, which ensure stable formation of a deposited coating, are determined. The use of a filler wire is found to redistribute the energy balance, to decrease the melting depth of the base metal, and to increase the surfacing speed.
