Experimental study of sensitivity of electromagnetic-acoustic transducers for flaw detection by nondestructive echo testing using bulk shear waves
Source abstract
Abstract
Results of experimental studies of sensitivity of electromagnetic-acoustic (EMA) transducers in the echo-testing mode are given. Flaws equivalent to reflectors shaped as disks and side surfaces of cylinders with diameters of 1 mm and more have been detected with a high probability in samples of rails, round and square blanks, and metal sheets. We have concluded that nondestructive echo testing of metals using EMA transducers can be performed with a sensitivity close to that of piezoelectric transducers.
