Time of Flight Diffraction (TOFD)
Highly effective ultrasonic detection and sizing of weld defects.
Time of Flight Diffraction (TOFD) is a highly effective ultrasonic technique for detecting and sizing weld defects. By measuring the time it takes for sound waves to travel to and from flaws, TOFD provides precise data essential for maintaining asset integrity and compliance.
TOFD delivers accurate through-wall sizing of planar flaws independent of beam angle, making it a cornerstone of automated weld inspection and fitness-for-service (API 579-1/ASME FFS-1) evaluation.
