TOFD探頭和楔塊可在鋼中產(chǎn)生折射縱波，可用于通過(guò)衍射時(shí)差技術(shù)對(duì)裂縫進(jìn)行定量的應(yīng)用中。
Advantages 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.
