Abstract

A part and method for repairing a high velocity fluid flow machine part, for example a turbine blade comprises an insert which may be made from a piece of material the same as the turbine blade and prior to attachment to the blade has an edge region hardened by any suitable means, for example induction hardening, the insert then being secured to the blade by welding or brazing, the weld or braze material being of a relatively soft nature to provide a cushion between the insert and the blade so as to minimize the occurrence of stress corrosion cracking.
