Abstract
A nondestructive method for a volumetric examination of a blade root of a turbine blade while the turbine blade is installed in a turbine shaft of a steam turbine includes installing the bracket onto the outer diameter of the turbine shaft where the bracket conforms to the geometry of the turbine blade and turbine shaft, positioning an ultrasonic phased array probe on a platform face of the turbine blade and rotating the bracket around the turbine shaft for generation of a scan of a portion of the blade root, generating a scan of the desired position by directing ultrasonic waves via the ultrasonic phased array probe, and capturing reflected ultrasonic waves by a receiver to generate the scan and comparing the scan to a reference scan of the blade root to determine defects within the blade root.
