Purpose and scope
Предназначена для автоматической сварки с принудительным формированием стыковых швов металлоконструкций из малоуглеродистых сталей по ГОСТ 380 и низколегированных сталей по ГОСТ 5521, ГОСТ 19281. Рекомендуется для сварки металла толщиной 10 – 30 мм. Типичные объекты применения: мостостроение, судостроительные конструкции, сварка арматуры железобетона класса А1...А2 в графитовых и медных формах.
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
Welding technology
-
During the welding process it is necessary to monitor the level of the slag bath and periodically pour excess slag over the edge of the slide.
-
When welding fittings, the welding technique is similar to welding with coated electrodes.
-
Use DC reverse polarity.
