TOFD uses diffracted ultrasonic signals from flaw tips for precise defect sizing and is often paired with PAUT.
Time-of-Flight Diffraction (TOFD) is an advanced ultrasonic technique that uses the time of flight of diffracted signals from the tips of defects to accurately determine flaw height and through-wall extent. TOFD is widely used for critical weld inspection and is often combined with PAUT to provide comprehensive inspection coverage.
