Repair Of A Shrouded Blade |
摘要 |
The present invention discloses a novel and improved method for repairing a shrouded blade and a reconditioned shrouded blade. More specifically, a way of measuring a set of previously-operated blades to determine their post-operation geometric characteristics is provided where an offset due to deformation of the hardface surfaces of the shroud is determined. The hardface surfaces of the shroud are rough-machined and blade-compatible material is added to the hardface surfaces. A first side hardface surface of the shroud is then machined to a desired dimension offset relative to an originally manufactured blade after which a second side hardface surface is machined such that the distance between the hardface surfaces satisfies the cross-shroud dimension, which is similar to that of an originally manufactured blade. |
