Phased Array Ultrasonic Testing (PAUT)

Energy Workforce provides advanced ultrasonic technique, Phased Array Ultrasonic Testing (PAUT) used for flaw detection, sizing, and imaging. PAUT technology is the ability to modify electronically the acoustic probe characteristics. Probe modifications are performed by introducing time shifts in the signals sent to (pulse) and received from (echo) individual elements of an array probe. Any ultrasonic testing technique for flaw detection and sizing can be applied using phased array probes.



  • Electronically controlled and selectable beam angles, beam focus and beam size
  • 100% encoded raw data storage and analysis
  • Fully color automatic real-time True-To-Geometry regular Sector Scan (S-Scan) or True-To-Geometry regular Linear Scan (B-Scan) displays with selectable A-Scan
  • ABI-Scan, Sector Scan, Tandem B-Scan based C-Scan and 3D Data Presentation
  • Fully functional Conventional flaw detector with multiple gates, trigonometric functions and setup and A-Scan memory
  • Codes compliant


3D Data Presentation


  • Speed; for welds, corrosion and other components, linear (or line scanning)
    scanning can increase scanning speed (and hence reduce costs) significantly
  • Imaging; S-scans, E-scans and other 2D and 3D imaging can give much better
    and more interpretable defect assessments
  • Flexibility; phased arrays can perform a wide variety of scans, for a wide variety
    of defects on many different types of components
  • Data storage; full or even partial data storage and display allows better defect
    interpretation, plus can be used for archive purposes
  • Fast scanning speed, and cost-effectiv
  • Improve the Probability of Detection
  • Multiple angles from one probe at one location are used instead of using a raster motion and multiple wedges
  • Greater flexibility for inspection of complex geometries
  • Give more data in the available time
  • Very sensitive to all kinds of defects
  • Capability to modify the refracted angle of the beam generated by the array probe
  • Can replace costly and hazardous radiography applications
  • Minimize false calls
  • Higher confidence in results
  • Excellent far field resolution
