Method of repairing shrouded turbine blades with cracks in the vicinity of the outer shroud notch

摘要

A method of repairing a damaged notch fillet radius (20) of a turbine blade shroud (12) includes a replacement notch fillet radius (20) and a hardface nugget (30). The damaged notch fillet radius (20) is blended out and a hardface structure (22) positioned proximate the damaged notch fillet radius (20) is removed. A replacement notch fillet (20) radius is formed with weld filler and the hardface nugget (30) is welded to at least a portion of the replacement notch fillet radius (20).
