Phased Array Ultrasonic Testing (PAUT)

Phased Array Ultrasonic Testing (PAUT) is an advanced application of ultrasonic testing technology. It can be used for weld inspections, crack and flaw detections, thickness measurements and corrosion inspections. Because of the detailed visualization of the defect size, shape, depth and orientation, Phased Array can often be used instead of Radiographic Testing. Since it does not use ionizing radiation, there is no need to create a safety zone which usually means interrupting production.

ADVANTAGES OF

PAUT

  • Quick setup and simple inspection process
  • Suitable for wide range of materials
  • Suitable for complex test piece geometries
  • Applicable on material thicknesses from 3,2 to 200 millimetres
  • On stream inspection up to 400°C
  • No harmful ionising radiation
  • No need to interrupt production
  • Exact information about indication length and depth
  • Scanning large areas without moving the probe
  • Inspection data represented visually
  • Direct interpretation of results
  • Inspection data available in digital format
