Ultrasonic Testing (UT) utilizes sound energy at high frequencies to provide examinations and measurements of the product. This test aids in flaw detection/evaluation, dimensional measurements, etc. When the wave path moves over a discontinuity, the flaw reflects back some of the wave’s energy. This flaw signal is converted into an electrical signal by a transducer, creating a reading on the display device. Ultrasonic testing, which is often used to test thicker sections accessible from only one side, is typically able to detect finer linear or planar defects in a welded tubular product than Radiography (or x-ray) testing can.
