Ultrasonic flaw detection is a powerful nondestructive testing (NDT) technology and a well-established test method in many industries. However it can seem complex to a person who has not worked with it.

Modern ultrasonic flaw detectors are small, portable, microprocessor-based instruments suitable for both shop and field use. They generate and display an ultrasonic waveform that is interpreted by a trained operator, often with the aid of analysis software, to locate and categorize flaws in test pieces. The detector will typically include an ultrasonic pulser/receiver, hardware and software for signal capture and analysis, a waveform display, and a data-logging module. Although some analog-based flaw detectors are still manufactured, most contemporary instruments use digital signal processing for improved stability and precision.
