Phased Array UT

Phased Array Ultrasonic Testing (PAUT)

Phased Array Ultrasonic Testing (PAUT) is a highly advanced and specialist ultrasonic inspection method, offering a safe and effective alternative to radiographic (X-ray) inspection. PAUT produces detailed images of the inspected area without exposing personnel or the public to radiation, making it particularly suitable for live sites and restricted environments.

Unlike conventional ultrasonic testing, which requires the probe to be physically moved to cover the area of interest, PAUT uses electronically controlled beam steering and focusing to inspect a large volume of material from a fixed probe position.

PAUT probes are made up of multiple small elements, each of which can be pulsed independently at precisely calculated time intervals. This allows the ultrasonic beam to be focused, angled, and swept electronically, providing comprehensive coverage of the weld or component.

The term “phased” refers to the controlled timing of the pulses, while “array” describes the multiple ultrasonic elements within the probe.

PAUT provides:

• High probability of defect detection

• Accurate defect sizing and positioning

• Clear, image-based results

• Permanent digital inspection records
