PROBLEM TO BE SOLVED: To improve a torch for consumable electrode gas shielded arc welding which performs the welding by supplying two wires or more in the consumable electrode gas shielded arc welding. SOLUTION: This torch for consumable electrode gas shielded arc welding is constituted in such a manner that two torches or more having axial insertion holes for wire insertion are juxtaposed, feeding chips which feed power to the wires by making the wires internally contact with the feeding chips are screwed into the tip parts of the torches, the tip parts of the torches are surrounded by a nozzle 53 and shielding gas 55 is supplied to the inside of the nozzle 53. Therein, chip bodies 49, 50 are attachable and detachable to and from the tip parts of torch bodies 43, 44 which are disposed in the torches and, further, this torch for consumable electrode gas shielded arc welding has a shape in such a manner that the angle of the insertion holes through which the wires of chip bodies are inserted, the tip distance of the feeding chips which are screwed into the tip of the chip bodies and the inclination angle with respect to the vertical line when the chip bodies are mounted on the torch bodies are suitable for the bodies to be welded and the welding method.
