Transceiver Delay Line (TOFD)
Acrylic delay line for testing for discontinuities with the TOFD method (time of flight diffraction)
A special probe is used in the testing for discontinuities with the TOFD method (time of flight diffraction). This consists of a transmitter probe and a receiver probe, which are guided over the surface of the test object at a particular angle and a fixed distance to each other. Such a transmitter-receiver or dual-element probe can be put together with this delay line and two GAMPT probes of the same frequency.
Material: acrylicund velocity (acrylic): ≈ 2700 m/s (longitudinal)
Angle of incidence: 38°
Resulting angle of the shear wave in aluminium (c ≈ 3100 m/s): 45°
