Abstract
A process for producing a small crack in a turbine rotor blade for use in training inspectors to be qualified for inspecting blades with small crack, where each blade is vibrated in order to initiate a small crack under observation using an IR camera that can detect for a small crack, and when a small crack at a desired size is produced on the blade, the vibration is stopped and the blade removed and then used in a training process to train and qualify an inspector for an inspection process.
