    • The present disclosure relates to an overhead submerged arc welding process wherein a flux for the submerged arc welding is supplied from the underside of the welding line while at the same time a consumable electrode is supplied from the underside of the welding line, the process being characterized by maintaining the interrelationship between a flux supply cylinder and the plates to be welded such that the length from the under surfaces of the plates to be welded to the upper end of the open flux supply cylinder and the diameter D of the opening at the end of the flux supply cylinder is represented by the formula 2.ltoreq.D/I.ltoreq.15.
    • 本公开涉及一种架空埋弧焊接工艺,其中用于浸没电弧焊接的焊剂从焊接线的下侧供应,同时从焊接线的下侧供应可消耗电极,该工艺被表征 通过保持焊剂供应圆筒和待焊接的板之间的相互关系,使得从待焊接的板的下表面到开放式焊剂供应圆筒的上端的长度以及在开放焊剂供应圆筒的端部的开口的直径D 磁通供应气缸由公式2表示:D / I
