What is a PAUT inspection?

A PAUT inspection, or Phased Array Ultrasonic Testing, is a non-destructive testing (NDT) method that uses beam technology to detect asset flaws and defects.

PAUT fist became available in a portable form for commercial use in the 1990s.

The PAUT method scans an asset using multiple elements at once. In fact, NDT technicians can use anywhere from 4 to 64 elements to scan a single asset. The technician receives images of the scanned areas in A, B, C, and D forms, which can then be combined to create a 3D image of the area. This allows for a significantly higher probability of detection over traditional manual ultrasonic testing (UT) methods.
