description An ultra-flat non-consumable electrode welding torch which allows performing a welding operation through a narrow gap between adjacent piping such as welding piping of a boiler panel, to be mounted on a compact automatic welding head, and a welding head provided with such a welding torch are to be provided. As a gas supply mechanism that supplies a shield gas to a welding section formed at the tip of the non-consumable electrode through inside of the torch body for the non-consumable electrode welding, a gas supply path is provided for supplying the shield gas from an outer gas space in a double ring shaped gas space provided around a non-consumable electrode and divided by a partition wall, to an inner gas space through a plurality of orifices provided at regular intervals in the partition wall, and the gas is blown from the inner gas space to the region around the non-consumable electrode through a metal mesh plate. A gas outlet opening provided in the inner gas space is oriented in a different direction from the gas blowing direction through the orifice.
