Method for repairing a turbine diaphragm and diaphragm assembly resulting therefrom

摘要

This disclosure describes embodiments of a method of repairing a diaphragm (102) found in a turbine, and a diaphragm assembly (100) resulting from the same, that does not require welds in between the partitions. The method inserts a replacement part (104) in place of certain machine-removed portions of the existing partitions on the diaphragm. The replacement part (104) includes coupons (120) that work in combination with the remaining portions of the partitions (112) to form the aerodynamic shape of the original partitions.
