Abstract

A method of working a gas turbine engine component, for example, a turbine airfoil platform having a heat crack, is disclosed. The presented method may allow turbine airfoils to be repaired, modified, manufactured or otherwise worked and subsequently assembled into a turbine section of a gas turbine engine. This method may help to reduce the costs of operating a gas turbine engine by allowing damaged turbine airfoils to be repaired rather than discarded.
