TOFD Training & Certification Course
Time-of-Flight Diffraction (TOFD) training for precision depth-sizing of planar weld flaws — probe-pair configuration and PCS calculation, lateral wave and back-wall echo interpretation, and the combined TOFD+PAUT technique used on pipeline and pressure-vessel welds per ASME Section V Article 4 and API 1104. Typically layered onto an existing UT or PAUT Level II certification. Online theory + on-site practical. See our PAUT Level 2 training, UT Level 2 course, or the full training catalogue.
