Time of Flight Diffraction (TOFD) is a sensitive and accurate method for inspecting welds for defects.
TOFD uses two probes in tandem with a pitch-catch technique. Time of Flight Diffraction (TOFD) can detect transverse type defects, as well as accurately size for both the length and height of flaws.
