Patent

CA 2711281

The invention relates to a method for nondestructive testing of a test object 100 by means of ultrasound, which includes the following steps: a. radiating directed ultrasonic pulses into the test object 100 at an irradiation angle .beta., whereby the irradiation angle .beta. is set electronically, b. recording of echo signals that result from the ultrasonic pulses radiated into the test object 100, c. determining an ERS value of an error 102 in the volume of the test object from echo signals, which can be associated with the error 102. Further, the invention relates to a device for carrying out the method.

L'objet de l'invention concerne un procédé pour le contrôle sans destruction d'un échantillon d'essai 100 par ultrasons, lequel comprend les étapes du procédé suivantes : a. activation d'impulsions d'ultrasons ciblées dans l'échantillon d'essai 100 sous un angle d'incidence ß, l'angle d'incidence ß étant réglé électroniquement, b. réception de signaux d'échos qui résultent des impulsions d'ultrasons activées dans l'échantillon d'essai 100, c. calcul d'une valeur ERS d'une erreur 102 en volume de l'échantillon d'essai à partir des signaux d'échos qui peuvent être attribués à l'erreur 102. En outre, l'invention concerne un dispositif de réalisation du procédé.
