Abstract: In one aspect, the present disclosure is directed to a method for treating a region of a gas turbine component. The method includes heating the region to a first temperature. One or more surface discontinuities located in the region are welded such that at least a portion of the region is heated to a second temperature. The region is annealed at a third temperature. The second temperature is relatively greater than the first temperature, and the first temperature is relatively greater than the third temperature.
