PURPOSE: A tungsten-inert gas arc welding nipple is provided to minimize electric resistance and heat generation, and to prevent a gas pipe from being broken or damaged by the heat generation. CONSTITUTION: A tungsten-inert gas arc welding nipple includes a body part (100), a welding line (200), a gas feeding pipe (300), and a welding torch (400). One side of the body part is formed into a hexagonal column, and the other side of the body part has a threaded groove. The welding torch is in contact with the end of the threaded groove. A gas inlet hole at one end of the body part is connected to the gas feeding pipe, and a gas is fed to the welding torch through the same. The gas fed through the gas inlet hole is discharged through a gas outlet hole at the other end of the body part. |
