Abstract

The present invention proposes a technique for repairing, reconstructing or extending steam turbine diaphragm ring or web axially. The technique attaches a ring or multiple rings which are welded to the outer ring or inner web of any of the diaphragm. The rings are added either for an increased setback modification, steam seal face repair, diaphragm redesign or any other reason which requires material to be added to the diaphragm.
