Time of Flight Diffraction Ultrasonic Testing (T.O.F.D)

TOFD technique is rapidly gaining importance as a stand-alone inspection method and an advanced ultrasonic inspection technique that fulfils a need for reliable inspection. Defects are detected by the diffracted ultrasound wave occurring at the edges of defects. Due to its sensitivity and sizing accuracy, TOFD is an excellent tool for monitoring root erosion, stress corrosion cracking, vessel cladding and Hydrogen Attack.

Technique capability:

  • Ferrous & non-ferrous materials can be inspected.
  • Precise defect sizing.
  • High probability of defect detection.
  • High speed weld inspection.
  • High speed cladding surface corrosion.
  • screening.
