Phased Array Ultrasonic Inspection of Structural Bolts Using Creo Bolt Scanner

Abstract

Structural bolts are crucial in ensuring the safety and reliability of buildings, infrastructure, pipelines, and bridges. This paper comprehensively examines structural bolts using Phased Array Ultrasonic Testing (PAUT) and Total Focusing Method (TFM) with the Creo Bolt Scanners. The study aims to highlight the advantages and capabilities of this advanced inspection technique in both structural steel building and bridge applications. The inspection trial involved bolts with induced cracks and notches simulating defects. PAUT scans were performed in a circular pattern from both ends of the bolt, and TFM scans were employed to enhance flaw visibility in specific regions.
