Time-of-Flight
Diffraction (TOFD) is now
a widely used UT technique capable of both cost-effective flaw
detection and high accuracy flaw sizing. In recent years, its
recognition in codes and standards, the ready availability of modestly
priced TOFD capable instrumentation and access to training
courses and certification schemes has lead to many inspection service
companies routinely offering TOFD inspection to thier clients. However,
while TOFD is at heart a simple and easy to understand
technique, in common with many other powerful
techniques, there are nuances and subtleties in its operation that need
to be understood and taken into consideration if optimum performance is
to be achieved.
KANDE personnel have many years experience of TOFD having worked with
it since its original development and commercialisation by by UKAEA in
the 1980s. In particular, we have world-class experience of
the design, qualification and application of TOFD inspections
in the nuclear power industry, including applications such as CRDM
nozzle inspection and nozzle inner radius inspection. This experience
has guided the development of our InSight software tool and of our
USBox instrument which offers a highly sophisticated TOFD inspection
tool at an entry-level price. In addition we can provide consultancy
and training on all aspects of TOFD inspection design and TOFD data
analysis, including 'non-standard' applications such as data
reconstruction in complex geometries and variable separation scanning.
