  • Ultrasonic testing method for a part of complex geometry
    Patent number: 6202489
    Abstract: An ultrasonic testing method for parts of complex geometry comprises using a multielement transducer transmitting focused ultrasonic waves into the part to be tested. The focusing of the ultrasonic waves is implemented in two different modes using multichannel control electronics. The two focusing modes are an electronic focusing mode and a time reversal focusing mode which are selected as a function of the depth of the particular test zone. The time reversal focusing mode is selected to test central zones located at the largest depths around the longitudinal axis of the part. The electronic focusing mode is selected to test intermediate zones situated at depths between the central zones and a peripheral zone of the part.
