A method for repairing damaged bolt holes in a flange having a plurality of circumferentially spaced bolt holes therein, with each bolt hole defining a center axis and the flange defining an outer diameter edge. The method includes removing parent material of the flange in a first pattern, and metallurgically joining a replacement detail to the parent material of the flange a location where the parent material of the flange was removed in the first pattern. The first pattern is bounded by first, second, third and fourth points. The first point corresponds to the center axis of a first of the plurality of bolt holes, the second point corresponds to center axis of a second of the plurality of bolt holes, and the third and fourth points are defined at the outer diameter edge of the flange circumferentially spaced from each other.
