| 摘要 |
The present invention relates to a TIG welding method of a first part with a first wall and an end edge to a second part with a second wall and an edge, both parts being welded to one another along a junction surface between said edges and along which the first wall forms a salient angle with the second wall. The method characterised in that the electrode is moved along said surface, the electrode being laid out on the side of the salient angle according to an angle (beta) with respect to the first wall smaller than 180°, the direction (D) of the electrode running through the re-entrant angle associated with the salient angle. The method is applied in particular to the welding of plug guides to a combustion chamber jacket of a gas turbine motor.
