    This paper discusses the development of an ultrasonic time of flight diffraction-based inspection technique for sizing surface-breaking vertical cracks in complex geometry plant components like a solid steam turbine rotor with integral discs. and J.A.G. Temple, Engineering Applications of Ultrasonic Time-of-flight Diffraction, second Author: S.K. Nath. Time of Flight Diffraction (TOFD) is an ultrasonic technique that offers the most efficient and cost effective inspection tool yet developed for the non-intrusive examination of plant equipment. TOFD differs from conventional pulse echo ultrasonics in that it depends on diffracted energy rather than reflected energy, monitored in the form of.

Sep 30,  · Abstract. Despite the recent popularity of ultrasonic time-of-flight diffraction (TOFD) as a reliable non-destructive testing technique for the inspection of weld defects in steel structures, the critical stages of data processing and interpretation are still performed photospace.site by: 1.

Time-of-flight diffraction method of ultrasonic testing is a sensitive and accurate method for the nondestructive testing of welds for defects. TOFD originated from tip diffraction techniques which were first published by Silk and Liddington in which paved the way for TOFD.

Later works on this technique are given in a number of sources which include Harumi et al., Avioli et al., and Bray and. The simulated ultrasonic time-of-flight diffraction (TOFD) A-scan signals for surface-breaking crack lengths 2 mm and 4 mm in a 10 mm thick aluminium specimen were compared quantitatively with the experimental results.
