1. A method for repairing a component having a substrate, the method comprising:
aluminizing the substrate, which produces a diffusion layer within the substrate and generates a build-up layer on the diffusion layer; removing only a part of the build-up layer, such that a region of a surface of the diffusion layer is exposed and a remnant of the build-up layer remains on the diffusion layer adjacent the exposed region of the diffusion layer; providing a weld to the region of the diffusion layer that is exposed next to the remnant of the build-up layer; and retaining the remnant of the build-up layer adjacent the weld after providing the weld.
