TURBINE BLADE REPAIR

摘要

A method of manufacturing or repairing a turbine blade (21) which includes removing a part (22) of a blade such as a damaged part and securing thereto an insert (25) of hard steel which has been hardened prior to secuirng to the turbine blade and is then welded to the turbine blade. Tempering and heat treatment processes may be carried out. The insert is hardened to a hardness greater than that eventually required since such hardness may be reduced during the securing of the insert to the the turbine blade.
