PROBLEM TO BE SOLVED: To provide a method of repairing a turbine component seal land. SOLUTION: The method comprises: (a) a step of removing material along substantially the entire seal land to provide a preform-receiving face; (b) a step of locating a repair preform along and engaged with the preform-receiving face; (c) a step of brazing the preform to the preform-receiving face; (d) and a step of finish machining an exposed face of the preform to specifications to provide the repaired seal land.

Abstract:
PROBLEM TO BE SOLVED: To provide a sealing method of liquid-cooled stator bar that surely and effectively prevents leakages occurring at the connection between the coupling and the wires of a water-cooled generator. SOLUTION: The method includes a step for blasting (42) the inner surface of the connection between coupling and wires with CO 2 pellet, in order to remove free cooper oxide that interfere with a proper sealing between an epoxy resin and the copper surface of the connection. After spraying pressurized air for cleaning the surface and removing particulate matters, an epoxy resin (44) is applied to a brazed connection, and then the connection between coupling and wires is evacuated. Next, the epoxy resin is made to filled surely into all the fractures or cracks on the connecting surface by releasing the vacuum, and the tendency of the epoxy resin to be peeled is minimized or eliminated.
