A method for the non-destructive testing of a unit under test, as well as devices for this purpose, by means of ultrasound.

摘要

The object of the invention is a method for the non-destructive testing of a test specimen 100 by means of ultrasound, which comprises the steps of:a. einschallen ultrasound pulses directed into the test piece 100 at an angle of acoustic irradiation β, wherein the ensonification angle β is set electronically,example, receive echo signals from the irradiated ultrasound pulses into the test piece 100 result,c. calculating a ers - value of a fault 102 in the volume of the test specimen of echo signals which can be assigned to the error 102.Furthermore, the invention relates to a device which is suitable for performing the method.
