TOFD探头和楔块
TOFD探头和楔块可在钢中产生折射纵波，可用于通过衍射时差技术对裂缝进行定量的应用中。
Our time-of-flight diffraction transducers are highly damped longitudinal wave probes that offer excellent resolution in challenging TOFD applications. These highly sensitive composite element broadband transducers are available in frequencies from 2.25 MHz to 15 MHz and in sizes from 3 mm (0.25") to 12 mm (0.50"). They are for use with specialized TOFD wedges designed to produce refracted longitudinal waves in steel.
