Webb1 dec. 2024 · The Ultrasonic Time-of-Flight Diffraction (TOFD) was first reported by Silk and Lidington [2] as a method that focus on diffracted waves, bringing many advantages in flaw assessment towards the previous conventional ultrasonic techniques, based mostly on reflected waves. WebbAbstract. The article is an comprehensive review of the TOFD technique. The author discusses many aspects, e.g., accuracy, repeatability, coverage, resolution, defect types, and last not least costs, where the real value of TOFD lies - despite its few inherent limitations. He concluded - yes, TOFD does have its limitations - but so do all other ...
