Summary:Special features of DGS-diagram-based sensitivity tuning of the ultrasonic testing of railway rolling stock's wheel-pair axles through the use of normal and angle probes from the end and lateral surfaces are considered. The possibility of collecting the reference signals by tuning with reference samples (without artificial reflectors of the "flat-bottom" type) was established. Examples of flaw detection using tuning of the acceptance level as per DGS diagrams based on the practice of acceptance inspection at OAO DMZ are given.
