A method for repairing a turbine blade is described. The turbine blade usually includes a root portion; an airfoil having a pressure sidewall and a suction sidewall; and a tip disposed between the two sidewalls. The method includes the steps of removing substantially all of an upper region of the tip, and then rebuilding only a portion of the upper tip region. The portion that is rebuilt generally extends from the suction sidewall. Another embodiment is directed to a method for repairing or modifying a turbine blade that includes a squealer rim extending above both a pressure sidewall and a suction sidewall of the airfoil. The squealer rim portion that extends from the pressure sidewall is removed, while leaving in place the squealer rim portion that extends from the suction sidewall. |
