🔍 BS 7704 / ASME Section V TOFD (Diffracted Tip Ultrasonic Waves Flaw Height mm)

Time-of-Flight Diffraction (TOFD) Calculator

Size Time-of-Flight Diffraction (TOFD) weld inspections for ultra-precise planar crack height sizing under BS 7704 & ASME Section VIII: calculate time-of-flight parabolic arrival curves (lateral wave, upper tip diffraction, lower tip diffraction, and back-wall echo), sizing flaw height within ±0.5mm accuracy, and engineering NDT margins.
