Design and Fabrication of an Ultrasonic Testing Probe Holder to Inspect Overhead Anchor Bolts

Download (673.14 kB)

This paper aims to study the design and fabrication of a novel ultrasonic testing probe holder for inspecting different types of carbon steel anchor bolts in an overhead position. There are many factors impacted by the new design of the probe holder, including test results quality, operating cost, inspection time, test efficiency, and inspection safety. The test consistency and time saved to inspect overhead bolts are the most important benefits for the new probe design, as it can obtain high-quality inspection results almost immediately with minimum manual operation required.
