FIELD: welding and surfacing of metallic parts. SUBSTANCE: activating material is in the form of core coated with envelope. The last is made of mixture of polymer and activating flux at next relation of ingredients, mass. %: activating flux, 5 - 80; polymer, 20 - 95. Core may be made of metallic wire or metallic band or from metal powder. Polymer is selected of group containing polytetrafluoroethylene, polyamide, polyimide. Density of surfaced metal is increased due to degassing welding bath and due to reducing oxides. EFFECT: enhanced quality of welded joints. 3 cl, 1 ex |
