Purpose and scope
Предназначена для механизированной сварки металлоконструкций из малоуглеродистых сталей по ГОСТ 380 и низколегированных сталей по ГОСТ 19281, втом числе эксплуатации при низких температурах. Применяется также для заварки дефектов литья из углеродистых и легированных конструкционных сталейм (15Л - 35Л, 20ГЛ, 20ГСЛ, 20Г1ФЛ, 30ГСЛ, 35ГЛ и др. им подобных) по ГОСТ 977. Типичные объекты применения: строительные металлоконструкции, транспортное машиностроение, узлы дорожных и строительных машин, элементов грузоподъемных устройств и т.п.
Welding and technological properties
-
Arc Stability - consistent and stable arc behavior, good weld bead appearance.
-
Slag completely covers the weld bead, and easy to remove slag. High crack and pore resistance.
-
Shielding gas.: 100% CO2, Ar + CO2
Welding technology
-
Welding in the lower position is performed at the location of the wire perpendicular to the weld bead or tilt «angle back».
-
It is possible to weld multi-layer welds without removing slag when making 3 layers.
-
Use DC reverse polarity.
