Time of Flight Diffraction (TOFD) is a reliable method of ultrasonic testing (UT) used to look for flaws in welds and is a non-destructive testing method. TOFD uses the time of flight of an ultrasonic pulse to find the location of a reflector. It can also be used for weld overlays and the heat affected zones of other components as well such as piping, pressure vessels, clad material, storage tanks, and structural steel

TOFD is an NDT technique that works by emitting sound waves into a component and measuring the return time.
TOFD measures the response time of low amplitude waves diffracted by the tips of cracks, while UT methods only measure high amplitude sound waves that reflect off the component.
TOFD is widely used for weld testing for both pre-service and in-service inspection. It ensures defects do not compromise the stability and integrity of welded structures.
TOFD is one of the most reliable NDT services that take place during production work. Thus, no downtime. It is also quick and accurate without the use of any harmful radiation.
