摘要： The invention relates to a method for the non-destructive testing of a test object (100) by way of ultrasound, said method comprising the following steps: (a) radiating directed ultrasonic pulses into the test object (100) at an irradiation angle β, said irradiation angle β being set electronically, (b) recording echo signals that result from the ultrasonic pulses radiated into the test object (100), (c) determining an irradiation position X0 in which echo signals can be recorded that can be associated with an error (102) in the volume of the test object, (d) determining the irradiation angle βmax for which the ERS value of the error (102) reaches its maximum at position X0, (e) changing the irradiation position X0→X1 on the surface of the test object (100), the change of the irradiation position being captured, (f) electronically adjusting the irradiation angle β in such a manner that the ERS value of the error (102) reaches its maximum in the changed irradiation position X1. The invention further relates to a device which is suitable for carrying out said method.
