Comprehensive method for evaluating results of ultrasonic testing of parts and components of rolling stock when adjusting the sensitivity for different reflectors by A. N. KIREEV, V. V. BYKADOROV, M. A. KIREEVA

“…The article proposes a new integrated method for estimating discontinuities in parts and units of railway rolling stock according to the amplitude — distance — diameter diagrams by the standardless method with the possibility of determining the type of discontinuity by the dual-frequency method of flaw-detection with a manual ultrasonic testing with a single-channel ultrasonic flaw detector. Developed method is most relevant in the control of cast parts of railway rolling stock, since castings can be equally likely to contain bulk (pores, shells, nonmetallic inclusions, etc.) and planar discontinuities (cracks of different origin; flocks; segregations that lead to violation continuity, etc.). …”
