2. Ultrasonic testing - Wikipedia

   en.wikipedia.org/wiki/Ultrasonic_testing

   Ultrasonic testing ( UT) is a family of non-destructive testing techniques based on the propagation of ultrasonic waves in the object or material tested. In most common UT applications, very short ultrasonic pulse waves with centre frequencies ranging from 0.1-15 MHz and occasionally up to 50 MHz, are transmitted into materials to detect ...

3. Phased array ultrasonics - Wikipedia

   en.wikipedia.org/wiki/Phased_array_ultrasonics

   Phased array ultrasonics ( PA) is an advanced method of ultrasonic testing that has applications in medical imaging and industrial nondestructive testing. Common applications are to noninvasively examine the heart or to find flaws in manufactured materials such as welds. Single-element (non- phased array) probes, known technically as monolithic ...

4. Ultrasonic thickness measurement - Wikipedia

   en.wikipedia.org/wiki/Ultrasonic_Thickness...

   An ultrasonic thickness gauge is a measuring instrument for the non-destructive investigation of a material's thickness using ultrasonic waves . The usage of an ultrasonic thickness gauge for non-destructive testing to check material properties such as thickness measurement, is regular in all areas of industrial measurements.

5. Time-of-flight diffraction ultrasonics - Wikipedia

   en.wikipedia.org/wiki/Time-of-flight_diffraction...

   Time-of-flight diffraction ( TOFD) method of ultrasonic testing is a sensitive and accurate method for the nondestructive testing of welds for defects. TOFD originated from tip diffraction techniques which were first published by Silk and Liddington [1] in 1975 which paved the way for TOFD. Later works on this technique are given in a number of ...

7. Electromagnetic acoustic transducer - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_acoustic...

   Electromagnetic acoustic transducer. An EMAT ultrasonic transducer (UT) shown with a conventional piezoelectric UT. Electromagnetic acoustic transducer ( EMAT) is a transducer for non-contact acoustic wave generation and reception in conducting materials. Its effect is based on electromagnetic mechanisms, which do not need direct coupling with ...
