What does PAUT stand for?

PAUT stands for Phased Array Ultrasonic Testing. This NDT inspection method is a form of Ultrasonic Testing (UT) that uses sound waves to detect irregularities in different materials.

PAUT is often used to detect corrosion and changes in the properties of an asset, to measure the thickness of a material, and in welding to monitor quality and strength. With the use of PAUT, manufacturing flaws, in services flaws (e.g. corrosion and cracking) and parent metal flaws can be detected.

This ensures the safety and security of an asset and alerts NDT technicians to any defects that should be repaired or assets that need to be replaced.
