Abstract

PURPOSE: To perform welding making only the welding part an atmosphere of small amount of inert gas by sticking thin films soluble in solvent to inside and across two tubes on both sides of the weld zone and making welding supplying inert gas from the gap of butted part.
CONSTITUTION: Thin PVA films 3A, 3b are stuck to left and right tubes 1A, 1B crosswise at slightly inside from the end faces 2A, 2B and butted. A slender tube 6 is then inserted from the gap 5 of butted part into the space 4 formed by separation from both sides by two thin films 3A, 3B, and inert gas such as Ar is introduced through a rubber tube 7. Then, under this state, TIG welding is performed using a torch 8. The circumference of the tube is closed with the bead thus formed, and at the same time, the tube 6 is pulled out. The tube is then filled with water, and the thin films of PVA 3A, 3B are dissolved together with the adhesive and removed.
