METHOD OF MAKING PIECE ELECTRODE

摘要

FIELD: process engineering. ^ SUBSTANCE: invention may be used in producing coating composition and making piece electrodes. First coating layer from aluminium powder with higher sensitivity to oxygen is applied on bronze rod by plasma evaporation. Second layer containing slag-forming gas-forming components and is applied by dipping to prevent inner layer oxidation, thus, to reduce gas saturation of welding bath. ^ EFFECT: required chemical composition of built-up metal. ^ 1 tbl
