<p>Method of repairing a steam generator tube by means of a liner, in which the mechanical deformation (19) of the liner (15), by expansion in its end part opposite the expanded end (16) inside the tube plate (11), is located at a limited height, and the parameters of the mechanical deformation (19) are calculated in accordance with the welding parameters subsequently applied. These parameters are determined in accordance with the parameters of the initial mechanical deformation (19) so as to obtain relief of the stresses more particularly in the critical zones (19a, 19b) of the mechanical deformation.</p> |
