Purpose and scope
Предназначена для механизированной сварки металлоконструкций из малоуглеродистых сталей по ДСТУ 2651 (ГОСТ 380) и низколегированных сталей по ГОСТ 19281 общего назначения с содержание углерода не более 0,25%. Типичные объекты применения: строительные металлоконструкции, транспортное машиностроение, технологические емкости, сосуды, резервуары и трубопроводы, узлы дорожных и строительных машин 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». Welding of vertical joints is possible with the “bottom-up” and “top-down” methods with the wire positioned “forward angle” or perpendicular to the joint.
-
Welding of rust-coated and gas-treated or plasma-cut edges is not allowed.
-
Use DC reverse polarity.
