The method comprises the following steps: - depositing a buttering (19) with a closed contour on the inner surface (3) around the defined area (1); - installing a cap (27) at the defined area (1); - forming a weld (29) to weld the cap (27) to the buttering (19). The cap (27) comprises a concave area (31), the concavity of which is turned away from the defined area (1), the method comprising a step of radiographically inspecting the weld (29), carried out by placing a radioactive source (33) in the concave area (31).
