TOFD (Time Of Flight Defraction) is one of the Ultrasonic Testing methods most widely used in tank floor testing and for vertical discontinuities such as crack sizing. TOFD can be used on its own or in conjunction with PAUT Phased Array Ultrasonic testing to provide 100% coverage, highest probability of detection, accuracy of measurement and precise sizing of a discontinutiy. 

TOFD – Ultrasonic Time of Flight Diffraction testing (Encoded data acquisition and discontinuity mapping) is Fast, Accurate, Traceable, and Archivable a digital paper trail

Our Advanced Non Destructive Testing NDT inspection solutions cover:

  • Advanced Weld Inspection Solutions
  • Advanced Corrosion Inspection and detection
  • Advanced Stress Corrosion Inspection and detection
  • Advanced Tube Inspection
  • Advanced Composite Inspection
  • Weld root erosion testing in fluid carrying pipelines, high pressure steam pipes in power stations and refrigeration plants
  • Fatigue crack sizing & monitoring to continue plant operation safely before reaching critical crack size
  • Stress corrosion cracks & Creep cracks mapping & monitoring

The use of TOFD as an Advanced NDT inspection solution enables crack dimensions to be measured more accurately, so that expensive components and equipment can be kept in operational service as long as possible with minimal risk of failure.
