Phased Array Ultrasonic Testing (PAUT) is an advanced non-destructive examination technique that utilizes an array of ultrasonic testing probes, each of which is pulsed individually with computer-calculated timing (phasing).
The beams from the probes can be steered at different angles, focused at different depths, or multiplexed over the length of a long array, giving an image of the test item and its defects with high resolution.
PAUT can be used to inspect almost any material where traditional Ultrasonic Testing methods have been utilized and is often used for weld inspections and crack detection.
