| description | PROBLEM TO BE SOLVED: To provide the TIG welding torch which easily conducts weaving welding for an inner face of a narrow part and is easily produced at a low manufacturing cost. SOLUTION: The TIG welding torch is constructed so that a shield gas is caused to flow around an electrode bar 21 fixed to a torch main body 20, an arc is generated between the electrode bar 21 and a base metal, a cooling medium is circulated in the torch main body 20, welding is done while cooling the electrode bar 21 and its surrounding. In the welding torch, the torch main body 20 is a slender shape, while a cross sectional shape of its biggest part is formed to roughly round, an electrode fixing part 24 is arranged inside the torch main body 21, by mounting a bolt 25, which presses the electrode bar 21 to the electrode fixing part 24, to a torch main body tip and by holding the electrode bar 21 with the electrode fixing part and the bolt 25, the electrode bar 21 is fixed to the torch main body 20. |
