Patent ID: 8402830

Claim:
A method for nondestructive testing of a test object by means of ultrasound, which comprises the following steps: a. Radiating directed ultrasonic pulses into the test object at an irradiation angle β, whereby the irradiation angle β is set electronically, b. recording of echo signals that result from the ultrasonic pulses radiated into the test object, c. determining an ERS value of an error in the volume of the test object from echo signals that configured to associated with the error by means of a comparison of a majority of the stored reference values and by calculated compensation of the influence of the ERS value of the error that is to be determined by changes in the irradiation angle β, whereby the compensation takes at least one of the following changed sizes into consideration: Change of the virtual ultrasound converter size, change of the position of the injection point, change of the sound path or change of the focus.
