Abstract

We suggest using higher harmonics of the induction transducer output as sources of valuable information in tests of mounting hardware (nuts and bolts) by the method of high-frequency magnetic flux. In this case, spurious signals due to interfering features, such as edges of nut faces, are notably lower than in measurements of first harmonics. An instrument has been designed for testing two types of mounting hardware (nuts and bolts), which enables the operator to estimate flaw parameters and compare to those prescribed by the standards.
