  • Method of repairing a turbine blade and blade repaired thereby
    Patent number: 6996906
    Abstract: A method of repairing a turbine blade and the blade repaired thereby. The blade comprises a platform that has become bowed as a result of high temperature creep, with the result that the platform has a concave surface and an oppositely-disposed convex surface. The method generally comprises welding the concave surface to build up a weldment on the concave surface, cooling the weldment during which the weldment shrinks, the convex surface becomes flatter, and the concave surface beneath the weldment becomes flatter, and then removing a surface portion of the weldment so as to create a substantially flat weldment surface overlying the substantially straightened concave surface.
