Abstract: A method of repairing a stator stage is disclosed herein. The method includes receiving a stator stage including a plurality of stator vanes disposed between an outer diameter and an inner diameter, analyzing the stator stage for defects, determining based on the analysis that there is a first defect on an edge of a first stator vane of the plurality of stator vanes, removing a portion of the first stator vane including the first defect to form a first scallop on the edge of the first stator vane, repairing the first stator vane including filling the first scallop to fill the first stator vane to its original size and shape creating a repaired portion, and performing a blending process to the stator stage including the first stator vane and the repaired portion to smooth the plurality of stator vanes.
