Abstract
A method of manufacturing or repairing a turbine blade which includes removing a part of a blade such as a damaged part and securing thereto an insert of hard steel which has been hardened prior to securing to the turbine blade and is then welded to the turbine blade temporarily and heat treatment processes may be carried out and it is desired that 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 turbine blade.
