THREE-FREQUENCY METHOD FOR DETERMINING THE EQUIVALENT SIZE OF THE DISCONTINUITY DURING MANUAL ULTRASOUND CONTROL

Abstract

The work is devoted to topical issues of increasing the reliability and informativeness of the results of manual ultrasonic inspection of parts and assemblies of technical objects. The paper presents a three-frequency method of ultrasonic flaw detection, which makes it possible to increase the reliability of the non-etalon method for determining the type of discontinuity detected as a result of ultrasonic testing. The developed method makes it possible to determine the type of discontinuities of various types. The NDTRT-26 software product has been developed to automate calculations using the three-frequency method.
