Abstract
A method and a device for the near-surface, non-destructive inspection by means of ultrasound of a rotationally symmetric workpiece having a diameter that changes from section to section are provided. The method and device are based on the insonification of an ultrasonic test pulse into the workpiece at a defined insonification angle and the subsequent recording of an ultrasonic echo signal from the workpiece. Echo signals that trace back to a near-surface region ROI of the workpiece are identified and evaluated. Then, a graphic representation of the surface of the workpiece is generated.
