摘要
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.
