FLUX CORD WIRE FOR UNDERWATER WELDING BY WET METHOD

摘要

FIELD: metallurgy.;SUBSTANCE: charge in steel cover contains the following component ratio, wt %: rutile concentrate 23-42; ruddle 18-27; iron powder 28-42; ferromanganese 3-8; nickel 3-5; alkaline metal complex fluoride 5-18.;EFFECT: wire has good welding processing characteristics, it provides microdrop transfer of molten metal, arc stability and higher quality of welded joints due to active metallurgic reactions on binding of water vapour with hydrogen.;2 cl, 1 tbl
