An ultrasonic pulse is emitted at one end of the bolt; it runs through the bolt and is reflected at the opposite end as an echo which returns to the test head. The time for the ultrasonic pulse to travel between each end of the bolt is used to measure the bolt elongation. When calibrated, this allows control of bolt forces applied.

Apr 01, 2018 · In this paper, the problems and pitfalls associated with various ultrasonic techniques for measuring stress in bolts, is discussed. An ultrasonic technique developed for measuring themore » stress in Durehete 1055 bolts is presented. Material from a textured rolled bar has been used as a test bed in the development work.

The ultrasonic measurement of bolt tension is achieved by introducing a sonic pulse at one end of the fastener and accurately measuring the time of flight (TOF) required for the echo to return from the opposite end. Using material constants, the USM-3 converts this TOF into an “acoustic length” of the fastener, providing a baseline from ...

9 Rock Bolt s Integrity Testing Ultrasonic Guided Waves: Principle: A short duration Gaussian windowed sine burst is used to excite a guided wave in the bolt from the free end. The wave is then reflected from the other end and from any major defects. From the reflection arrival time and knowledge of the wave velocity dispersion curves, the positions of the defects or the bolt length can be ...
