RR433 - Safety implications of TOFD for in-manufacture inspections

Time of Flight Diffraction (TOFD) is an ultrasonic non-destructive testing method which was originally developed as an accurate method for measuring the throughwall extent of defects which had been detected by more conventional methods such as Pulse-Echo (PE) ultrasonics.

This report describes the results from a project to evaluate the safety implications related to the European project "Effective application of TOFD method for weld inspection at the manufacturing stage of pressure vessels".
