Abstract
PURPOSE: To prevent shielding gas from flowing out and a W electrode from being oxidized and burned by mounting a flange-shaped jig for preventing the flow-out of shielding gas on the pipe end side of a sleeve-shaped jig for tracing pipe inside diameter at the time of joining a pipe body into the insertion hole of a tube plate by automatic TIG welding.
CONSTITUTION: A flange part 8 for hermetically sealing a pipe hole by abutting its end edge to a tube plate 2 is provided to the pipe end side of a welding torch 6 which functions as a sleeve-shaped jig for tracing pipe inside diameter. The axial size (a) of the flange part 8 is so adjusted that a predetermined welding position is automatically set in a W electrode 3. The welding torch 6 mounted with the flange part 8 is inserted into a pipe 1 until the leading end of the flange part 8 contacts the tube plate surface to prevent the shielding gas such as Ar led into between the welding torch 6 and an electrode holder 4 from flowing to the outside at the welding and hermetically seal the weld zone. The welding work is performed in the atmosphere substituted completely by the shielding gas, whereby the W electrode is prevented from being oxidized and burned.
