Abstract
An apparatus for ultrasonically inspecting a component comprises a first ultrasonic transducer for transmitting an ultrasonic signal into a component having rotational symmetry and a second ultrasonic transducer for detecting the reflected, or transmitted, ultrasonic signal. A motor and a turntable produce relative rotation between the rotationally symmetrical component and the first and second transducers. Motors, a carriage and tracks on a frame provide relative radial motion between the rotationally symmetrical component and the first and second transducers to scan the whole of a surface of the rotationally symmetrical component. An ultrasonic signal analyzer analyses the detected ultrasonic signal by monitoring for ultrasonic signals having an amplitude above a predetermined amplitude and not having rotational symmetry and a display provides an indication that any detected ultrasonic signals above the predetermined amplitude and not having rotational symmetry is a potential flaw in the component.
