Phased Array Ultrasonic Testing (PAUT)

Phased array ultrasonic testing (PAUT) provides a fast and reliable solution for flaw detection and characterization.

PAUT is commonly used to inspect girth welds and longitudinal weld quality and to examine components with complex geometries.


  • Near real-time inspection results
  • Repeatable/Consistent
  • Can be used to create detailed and accurate cross-sections of parts.
  • Safe
  • Versatile
  • Portable
  • Highly accurate defect sizing: linear and vertical height
