Kireev A.N.  Tuning temporal sensitivity adjustment function with the help of ADD diagrams in ultrasonic inspection of rolling stock's rolled wheel centers

The paper offers a method for standardless tuning of ultrasonic flaw detector's temporal sensitivity adjustment function with respect to specific amplitude/distance/diameter diagrams. The method aims at ultrasonic inspection of wheel rims and bosses of rolled wheel centers for inadmissible internal axial cracks. It allows to equalize the amplitudes of echo signals from equal-size reflectors in the wheel center over the whole of the inspection range subject to the changes the changes of ultrasound attenuation factor change across the rim's or boss's section. NDTRT-05.01 software suite was developed to automatize the tuning process.
