PROBLEM TO BE SOLVED: To improve a method for completing arc welding in which two wires are fed in one torch for welding, in consumable electrode arc welding. SOLUTION: In the method for completing consumable two-electrode arc welding in which two wires are fed in one torch for welding, the feeding and energizing of a succeeding wire 4 are stopped at a welding completion position P2; while the welding torch is moved by a first crater fill distance D1 at a speed slower than the regular welding speed in the direction reversed from the welding direction, the first crater fill is performed by a preceding wire 3; and then, with the movement of the welding torch stopped, a second crater fill is performed by the preceding wire 3.
