A method is provided for repairing a turbine engine component (20). This method includes: machining away a worn land surface of an annular seal land (46A: 46B) to provide the annular seal land (46A; 46B) with a machined base surface (66A; 66B), the turbine engine component (20) including the annular seal land (46A; 46B), the annular seal land (46A; 46B) extending axially along an axis (32) to the machined base surface (66A; 66B), and the machined base surface (66A; 66B) extending circumferentially around the axis (32); brazing a repair ring (60A; 60B) to the machined base surface (66A; 66B) to provide a seal land preform; and machining the repair ring (60A; 60B) of the seal land preform to provide the turbine engine component (20) with a repaired seal land (46A; 46B) having a repaired land surface (78A; 78B), the repaired seal land (46A; 46B) extending axially along the axis (32) to the repaired land surface (78A; 78B), and the repaired land surface (78A; 78B) extending circumferentially around the axis (32).
