Welding torch

A welding torch comprising:

• a non-consumable electrode extending along an axial direction;
• a first member with a cylindrical shape disposed outwardly of the non-consumable electrode in a radial direction;
• an inner nozzle disposed outwardly of the non-consumable electrode in the radial direction and at one side in the axial direction with respect to the first member;
• an engaging member disposed outwardly of and covering a first end of the first member at the one side in the axial direction to a second end of the inner nozzle at another side in the axial direction, the engaging member coming into engagement with the first member and the inner nozzle;
• an outer nozzle disposed outwardly of the inner nozzle in a radial direction;
• and
• an electrode extrusion member disposed outwardly of the non-consumable electrode in the radial direction and inwardly of the inner nozzle in the radial direction,
• wherein the electrode extrusion member is concentrically disposed outwardly of the non-consumable electrode, and the inner nozzle is concentrically disposed outwardly of the electrode extrusion member,
• a first gas flow path for flowing a first inert gas is provided between the non-consumable electrode and the inner nozzle, and
• a second gas flow path for flowing a second inert gas is provided between the inner nozzle and the outer nozzle.
