Abstract

PURPOSE: To save slag removing work and improve low temperature toughness by setting groove width in the specified range according to the plate thickness of base metals, specifying welding current, voltage and welding heat input and making inter-electrode distance more than the specified length.
CONSTITUTION: Groove width is set according to the plate thickness of the materials to be welded. Namely, when plate thickness ≤20mm, it is set at 1/2 plate thickness ≤ groove width ≤ (plate thickness+succeeding wire diameter), and when plate thickness >20mm, it is set at 1/2 plate thickness ≤ groove width ≤ plate thickness. In addition, the welding current of the preceding electrode is regulated at 800W1350A, welding voltage at 30W36V, the welding current of the succeeding electrode at 600W1200A and welding voltage at 37W50V respectively. Further the welding heat input of the respective electrodes is kept at 60K J/cm or under and the inter-electrode distance between the preceding and succeeding electrodes is made 500mm or over. After the weld slag 4 formed by the preceding electrode 2 has solidified, a molten pool 3' is formed by the succeeding electrode 2' without separating and removing this slag 4, whereby welding is progressed.
