Purpose and scope
Предназначена для механизированной сварки (и наплавки) малоуглеродистых сталей ГОСТ 380, низколегированных сталей ГОСТ 19281, а также легированных конструкционных сталей ГОСТ 4543 с аустенитными сталами ГОСТ 5632. Также может применяться для сварки и ремонта ковшей карьерных экскаваторов, наплавка буферного слоя при нанесении твердосплавного покрытия, наплавка углеродистых и среднеуглеродистых сталей, ремонт трамвайных рельс, наплавки ж/д рельсов, крестовин, деталей стрелочных переводов. Рекомендуется для сварки металла толщиной более 5 мм.
Welding and technological properties
-
Arc Stability - consistent and stable arc behavior, good weld bead appearance. The wire provides deep penetration of the base metal.
-
Slag completely covers the weld bead, and easy to remove slag. , separability in deep cuts satisfactory.. High crack and pore resistance.
Welding technology
-
Welding in the lower position is performed at the location of the wire perpendicular to the weld bead or tilt «angle back».
-
Welding of rust-coated and gas-treated or plasma-cut edges is not allowed.
-
Use DC reverse polarity.
