Using Automated Ultrasonic Testing for Pipeline Girth Weld Inspection
By using wireless modules for ultrasonic data transmission and remote crawler control, along with software designed to support calibration, an automated ultrasonic testing (AUT) system can address several common challenges in pipeline inspection. These include the need for heavy power-supply equipment, complex modeling and simulation procedures, prolonged calibration times across multiple channels, and complicated system assembly. When implemented effectively, such systems can support more efficient inspection of long-distance pipelines.
Introduction of System Features
The automated ultrasonic testing (AUT) system described in this tutorial employs phased array and time of flight diffraction (TOFD) techniques. Designed for pipeline girth weld inspection in harsh environments, including both onshore and offshore applications, it can be used alongside automated welding processes. The system’s advantages include high inspection efficiency, effective discontinuity detection, reliable inspection results, no radiation hazards, and the ability to perform inspection alongside other operations.
Key features of the AUT system include:
