Abstract: The invention relates to a method for representing echo signals that are obtained with the aid of an ultrasonic test apparatus used for non-destructively testing a test piece. Said ultrasonic test apparatus comprises a probe, especially an angled probe, a monitor with a display device for representing the received echo signals in an cross-sectional image such that at least one front face and a back wall of the test piece can be recognized. A flaw is detected from different arrangements of the angular probe, represented, and an error signal is determined. The test images are stored and then represented in a superimposed manner in an evaluation image such that the first and the second error signal can be recognized.

Abstract: The invention relates to an ultrasonic probe comprising: —a housing (20), which accommodates an ultrasonic transducer and has a contact surface for making contact with the surface (28) of a body (30) to be inspected; —at least one digital camera (36), which is allocated to the housing (20) and which is aligned in such a way that it registers the surface (28) of the body (30) and supplies a respective electronic image of sub-sections of the surface (28) of the body (30) at intervals; —a circuit for image processing (40), which has an image memory (42) for at least one electronic image that has been registered by the digital camera (36).
