摘要

PROBLEM TO BE SOLVED: To provide a dual wire welding torch and a method pertinent to the same.

SOLUTION: The welding torch includes a nozzle having a first welding wire guide which is constituted so as to orient a first welding wire in the direction of the first welding wire and a second welding wire guide which is constituted so as to orient a second welding wire in the direction of the second welding wire which is not on the same plane and deviated from the direction of the first welding wire. The welding method includes a step for moving the welding torch to the joint on a workpiece to be welded. The first welding wire is supplied through the first welding wire guide with which the direction of the first welding wire is defined during moving the welding torch and the second welding wire is supplied through the second welding wire guide with which the direction of the second welding wire which is not on the same plane and deviated from the direction of the first welding wire, is defined.
