Phased Array Ultrasonic Testing (PAUT)

A phased array transducer enables an ultrasonic beam to be electronically focused or swept in angle along the length of the array reducing the scanning requirement of Conventional transducers. Technique can be used in lieu of radiography in the correct Circumstances.

Ultrasonic phased array systems can potentially be employed in almost any test where conventional ultrasonic flaw detectors have traditionally been used. Weld Inspection and crack detection are the most important applications. Phased array produces accurate, detailed cross-sectional pictures of internal structures at fast inspection speeds. The Benefits of phased array technology over conventional UT come from its ability to use multiple elements and electronic time delays to create beams that can be steered, scanned, swept, and focused electronically for fast inspection, full data storage, and multiple angle inspections.
