SUBMERGED ARC WELDING METHOD FOR STEEL PLATE |
摘要 |
The present invention provides a submerged arc welding method attempting to enhance toughness of a welded zone with low heat input and capable of achieving deep penetration and a sufficiently wide bead width in welding a thick material at a weld speed of 3 m/min or less. In the submerged arc welding method, a first electrode at the head in a welding direction has a wire diameter of 3.9 to 4.1 mm, two electrodes are arranged on both sides holding a weld line therebetween at the tail end in the welding direction, the wire tip positions of the two electrodes on a surface of the steel plate are arranged on the same line vertical to the weld line, and a distance W (mm) between each of the wire tip positions and the weld line is 5 to 20 mm. |

1. A submerged arc welding method for a steel plate using three or more electrodes, wherein a first electrode at the head in a welding direction has a wire diameter of 3.9 to 4.1 mm, two electrodes are arranged on both sides holding a weld line therebetween at the tail end in the welding direction, the wire tip positions of the two electrodes on a surface of the steel plate are arranged on the same line vertical to the weld line, and a distance W (mm) between each of the wire tip positions and the weld line is 5 to 20 mm. |
