Purpose and scope

Сварка малоуглеродистых конструкционных сталей при нижнем положении швов. Рекомендуется для сварки металла толщиной более 5 мм. Допускается сварка металла, покрытого окалиной и небольшим слоем ржавчины. Восстановление геометрии деталей стального литья А732 (1А), А352 GrWCB. Полуавтоматическая сварка металлоконструкций из малоуглеродистых сталей ГОСТ 380 и низколегированных сталей ГОСТ 19281 общего назначения. Типичные объекты применения: строительные металлоконструкции, технологические емкости и трубопроводы, узлы сельхозмашин, железнодорожная техника. 

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. High crack and pore resistance. High wind 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».
  • It is recommended to avoid directing the arc directly to the root of the corner joints.
  • Welding should end with a smooth arc break.
  • Use DC reverse polarity.
