The paper deals with the features of measurement of the velocity of surface acoustic waves, using a contact transducer, in which the exciting and receiving parts are rigidly coupled. A new procedure is proposed for velocity measurement by such a transducer, using a reference sample. Measurement of surface wave velocity in steel samples was performed. The velocity in these samples was also measured, using laser ultrasonic technology for testing the new method. The effectiveness of the proposed procedure application is shown. 12 Ref., 5 Fig.
