Patent ID: 7694566

Claim:
A method of displaying echo signals obtained with the help of an ultrasonic test apparatus for non-destructive testing of a test body, the ultrasonic test apparatus having an angle beam probe, an emitter, which is connected to the angle beam probe and which generates initial pulses which it delivers to the angle beam probe, a receiver, which is connected to the angle beam probe and which receives echo signals, and a monitor with a display, which is connected to the receiver to display the echo signals received in a cross-sectional image in such a manner that at least one front face and one back wall of the test body can be seen, the method comprising: placing the angle beam probe onto a front face of the test body; isonifying ultrasonic pulses into the test body at a certain angle; finding and growing a flaw from a first location of the angle beam probe, the extension of the flaw with respect to the first location of the angle beam probe being obtained with the help of a reference block process and being displayed true-to-scale on the display of the ultrasonic test apparatus as a first flaw signal in a first measurement image; storing the first measurement image generated and an associated A-scan; finding and growing the same flaw from a second location of the angle beam probe, the extension of the flaw with respect to the second location of the angle beam probe being obtained with the help of a reference block process and being displayed true-to-scale on the display as a second flaw signal in a second measurement image; storing the second measurement image generated and an associated A-scan; displaying the first and the second measurement images in one single evaluation image in such a manner that the first and the second flaw signals can be seen, superposed; and showing in the first and the second measurement images and the evaluation image a sound path that is divided into legs, the different legs being shown differently each and the first and second flaw signals being respectively shown according to the sound path or the leg or both from which they originate.
