Investigation and characterisation of surface cracks in metal components using time of flight diffraction (TOFD) technique in comparison to alternating current field measurement (ACFM) technique / Jeffry Jamil

, 2014
This research describes an investigation and characterisation of Time of Flight Diffraction (TOFD) technique when it interacts with surface defects in metal component. Four steel plates of thickness 19 mm were used in this study.

Time of flight difraction - an alternate non-destructive testing procedure to replace traditional methods

, 2003
Time-of-flight-diffraction Technique (TOFD) is potentially one of the fastest methods of Non-destructive testing (NDT) since a weld can be characterized to a certain degree with one single traverse along its length with two probes.
