ABSTRACT:
A method of and apparatus for repairing turbine blades wherein the repair requires the input of considerable thermal energy during a welding or brazing operation for example. The method involves the step of pre-distorting the blade prior to the welding or brazing operation so that the distortion that is expected to occur during welding or brazing leaves the blade after repair in its proper position. A clamp means may be provided to prevent parts of an individual blade from being predistorted so as to localize the predistortion in the required area. A tool for predistorting the blade ensures that a physical force may be applied to a local area of the blade.
