Patent ID: 8714018

Claim:
Method for the non-destructive testing of a test object by means of ultrasound, comprising the following steps: a. insonification of directed ultrasonic pulses into the test object at an insonification angle β, wherein the insonification angle β is adjusted electronically, b. recording of the echo signals that result from the ultrasonic pulses insonified into the test object, c. determining an insonification position at which echo signals can be recorded which can be allocated to a flaw in the volume of the test object, d. determining an insonification angle βmax for which an equivalent reflector size (ERS) value of the flaw has a maximum value at the position X0, e. changing the insonification position on a surface of the test object, wherein the change of the insonification position is detected, and f. electronic tracing of the insonification angle β during the change of the insonification position, such that the ultrasonic pulses insonified into the test object strike the flaw always at the same position.
