Device for non-destructive testing of a unit under test, by means of ultrasound, method for the operation of such a device as well as a method for non-destructive testing of a unit under test, by means of ultrasound.

摘要

The invention relates to a device (1) for the nondestructive testing of a test piece by means of ultrasound. In this case, the device has (1) a control unit (10) which, for the control of a phased - array - ultrasonic probe (24) and of a display (12) is provided. The control unit (10) is designed so that the phased - array - test head (24) in the pulse - echo - operation to operate and the ensonification angle θ of the phased - array - test head (24) to control in the unit under test. The phased - array - test head (24) - echo pulse received from the test specimen is analyzed by the control device (10), wherein the control unit (10) a a - image (14) or / and a b - image (16) of a received pulse - echo on the display (12) represents. The present invention also relates to a method for operating such a device (1) as well as a method for non-destructive testing of a unit under test, by means of ultrasound according to the tcg - method with the use of a phased - array - ultrasonic probe (24).
