<p>The present invention provides a non-consumable electrode type semiautomatic welding system which enables high-speed and high-deposition welding. A non-consumable electrode type semiautomatic welding system is provided with: a welding torch (1) in which a non-consumable electrode (1) for generating an arc between an object to be welded and the non-consumable electrode itself, and a torch nozzle (5) for releasing shielding gas toward a molten pool of the object to be welded formed by the arc are provided; a wire feeding device (502) for feeding a welding wire (10) from the leading end of a feeding head (12) attached to the welding torch (1) via an attachment jig (14) to the molten pool of the object to be welded; and a welding power source device (501) for supplying electric power and the shielding gas to the welding torch (1). Any one or more among the welding torch (1), the wire feeding device (502) and the welding power source device (501) are constituted by using at least some of a welding torch, a wire feeding device and a welding power source device which a consumable electrode type semiautomatic welding system is provided with.</p> |
