FIELD: metallurgy.
SUBSTANCE: heat-resistant cord along the weld surface is mounted or glued. The facing charge is loaded on the surface limited with the cord. Surfacing is carried out by high-frequency generator operating at 66 kHz frequency. Heat-resistant asbestos cord is prepared by soaking in glass liquid solution, dried and hold in 5% alcohol rosin solution.
EFFECT: reducing the complexity of item and charge preparation and surfacing process.
