    • PURPOSE: A flux charged wire for two-electrode electro-gas arc welding, a two-electrode electro-gas arc welding method, and a two-electrode electro-gas arc welding device are provided to obtain excellent welding work efficiency and excellent low-temperature toughness. CONSTITUTION: In a two-electrode electro-gas arc welding method, a sliding copper plate(2) sliding upward is put on the surface side of a plate(1) to be welded and a fixed-type backing material is put on the rear side. Two welding wires(4,5) are arranged in a bevel in an isolated state to the surface side and the rear side. The bevel is welded through upright butt welding. The welding wires are flux charged wires. The welding wire of the surface side is vibrated in the plate thickness direction and welding is executed with the polarity of the welding wires reversed. A two-electrode electro-gas arc welding device has a welding trolley supplying the surface-side welding wire in the bevel and moving along the bevel, and a supply member supplying the rear-side welding wire to the position of the backing member side.
