FIELD: metallurgy.
SUBSTANCE: charge in wire steel cover contains the following component ratio, wt %: rutile concentrate 25-37; calcium fluoride 8-17; iron powder 32-45; ferromanganese 5-9; nickel 1-3; alkaline metal carbonate 3-7, alkaline metal complex fluoride 3-13.
EFFECT: wire has good welding processing characteristics, it provides microdrop transfer of molten metal, arc stability and better formation of welded seal and quality of welded joints due to active metallurgic reactions on binding of water with hydrogen.
