The most important welded joints and claddings are treated, however, all the welded joints and claddings could not be treated because there are around 60.000 in each steam generator. First, cladding of the inner surface of the primary head of the steam generator is described. Submerged-arc cladding with a strip electrode was used for this purpose. Then the production of the welded joints between a tube and a tube sheet is described. All 5428 tubes were joined to the tube sheet, at each end, by TIG welding, preceded by mechanical rolling-in and hydraulic expansion. Welding of a partition plate to the primary head and to the tube sheet is described in the third part of the paper. Both welded joints, i.e. the one between the partition plate and the tube sheet and the one between the partition plate and the primary head, are shown as macro sections.
