Time-of-flight diffraction (TOFD) transducers generate refracted longitudinal waves in steel. These highly damped probes provide a high resolution for ultrasonic testing of welds. Manufactured in composite and non-composite materials in a threaded housing for use with TOFD wedges.

Working closely with established NDT manufacturers, Technology Design offer a range of leading brand TOFD probes, to provide you with a convenient single source to purchase a complete inspection package.
