![]() ![]() ![]() The reflected wave signal is transformed into an electrical signal by the transducer and is displayed on a screen. ![]() When there is a discontinuity (such as a crack) in the wave path, part of the energy will be reflected back from the flaw surface. The sound energy is introduced and propagates through the materials in the form of waves. Driven by the pulser, the transducer generates high frequency ultrasonic energy. A pulser/receiver is an electronic device that can produce high voltage electrical pulses. To illustrate the general inspection principle, a typical pulse/echo inspection configuration as illustrated below will be used.Ī typical UT inspection system consists of several functional units, such as the pulser/receiver, transducer, and display devices. Ultrasonic inspection can be used for flaw detection/evaluation, dimensional measurements, material characterization, and more. Ultrasonic Testing (UT) uses high frequency sound energy to conduct examinations and make measurements. Introduction Basic Principles of Ultrasonic Testing ![]()
