UT Testing for Stainless Steel Plate

Ultrasonic Testing (UT) utilizes sound energy at high frequencies, in order to provide examinations and measurements of the stainless steel product. This aids in flaw detection/evaluation, dimensional measurements, etc.

The ultrasonic testing inspection system consists of several parts, including a pulser/receiver, a transducer, and a display device. A pulser/receiver produces electrical pulses. These high voltage pulses work with the transducer to generate ultrasonic energy. This sound energy travels through the stainless steel in the form of waves. When a discontinuity (i.e. a crack) is discovered in the wave path, some of the energy is reflected back from the flaw.  This flaw signal is converted into an electrical signal by the transducer, creating a meaningful display on the display device.
