FIELD: metallurgy.
SUBSTANCE: mould can be displaced relative to the part to be hard-faced and includes current-feed, mid and forming sections arranged in height and isolated. Circular open electromagnet is designed to affect the fluid hard-facing metal by magnetic field. Mid section has through cut-outs. Said mould is arranged in the gap of said open circular electromagnet secured at forming section bed. Heights of electromagnet wall and mould forming section wall are related as 1:2-1:3. The first independent power supply designed to heat the molten pool is connected to current feed section. The second source to generate ring magnetic field is connected to mid section. The third source is connected to open electromagnet.
EFFECT: higher metal resilience and strength.
