The Analisys of Ultrasonic Attenuation Measurements in Steel

The article represents authors contribution to the methodology development of standard procedures of ultrasonic attenuation measurements aimed to practical use. The variability analisys of attenuatiom measurement results of ultrasonic waves in steel is presented. Various influences of elements of testing system (probe, instrument, operater) are taken under consideration in experimental design. Data are presented for longitudinal waves of nominal frequency of 2 MHz.
