Abstract
The invention relates to a TIG (Tungsten Inert Gas) surfacing welding gun and a surfacing method for the inner wall of a double-water-cooled ultrasmall-caliber pipe. The small-caliber connection pipe exists in a container and a pipeline; the inner wall of the small-caliber connection pipe possibly needs to be subjected to surfacing of a composite layer; and due to limitation to the diameter of the inner wall of the connection pipe, the ultrasmall-caliber connection pipe has high difficulty in surfacing. On composition, the TIG surfacing welding gun comprises a fixed flange (2); the fixed flange is fixedly connected with a gun body (3); an air water conduit (1) is arranged in the gun body; and the gun body is connected with a spear (4); and the air water conduit is connected with the spear. The TIG (Tungsten Inert Gas) surfacing welding gun and the surfacing method are used for surfacing.
