Abstract
A method and a device for the non-destructive inspection of a rotationally symmetric workpiece having sections with different diameters by a non-destructive inspection technique, such as ultrasound, are provided. Within the context of the method, a test data set characterizing the material properties of the workpiece is generated by the inspection technique. An azimuth angle-dependent indicated value set is generated therefrom. Subsequently, a representation of the workpiece is generated, wherein the elements of the indicated value set are depicted in the representation in a spatially resolved manner. In particular, a graphic representation of the surface of the workpiece can be generated in which flaw signals are displayed that may have been found.
