Abstract
A method of repairing a turbine blade of the type having discontinuities such as lacing wire holes the method including the steps of driving a plug into any such discontinuity that is not in the immediate area that is likely to be subjected to consideration thermal energy as occurs during welding. The presence of the plug decreases the tendency for stress to concentrate around the discontinuity if the blade is subjected to stress caused by physical force or high temperatures.
