A method of repairing a turbine component seal land comprising:
- (a) removing material along substantially the entire seal land to provide a preform-receiving face;
- (b) locating a repair preform along and engaged with said preform-receiving face;
- (c) brazing the preform to said preform-receiving face;
- and
- (d) finish machining an exposed face of the preform to specifications, thereby providing a repaired seal land.
A method of repairing a seal land at a downstream or outlet end of a gas turbine transition piece extending between a combustor and a first stage nozzle, the seal land formed by one side wall of a U-shaped channel, the method comprising:
- (a) removing material along substantially the entire seal land to provide a preform-receiving face;
- (b) locating a repair preform along and engaged with said preform-receiving face;
- (c) brazing the preform to said preform-receiving face;
- and
- (d) finish machining an exposed face of the preform to specifications, thereby providing a repaired seal land within said U-shaped channel.
A gas turbine component comprising an end configuration with a seal land adapted to be engaged by a seal element;
- said seal land comprised of a clad preform brazed to the component.
