A method of repairing a diaphragm of a rotary machine includes removing an initial steam path from the diaphragm. The initial steam path includes a plurality of initial partitions. Each initial partition is associated with an original trailing edge profile and an original axial length. The method also includes coupling a replacement steam path to the diaphragm. The replacement steam path includes a plurality of replacement partitions. Each replacement partition has a replacement axial length that is greater than the original axial length.

Method for repair of a diaphragm of a rotary machine

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