Fast and Efficient Welding Inspection of Structural Steel Using Adaptive Phased Array Ultrasonic NDT

The purpose of this study is to conduct a comprehensive assessment towards a technical guideline and recommendations for fast and efficient ultrasonic non-destructive testing (NDT) methodology and procedure for full inspection of welding and weldment in steel structures based on phased array ultrasonic testing (PAUT) technique. The study aims to provide information toward understanding the potential types of defects and flaws in weldment of steel structures, the significance of effect of flaws on quality of the welding and importance of their detection and assessment. The current ultrasonic NDT techniques will be evaluated for their performance in required welding inspection. Ultimately, the goal is to study the advanced PAUT technique as a potential NDT method for efficient and accurate welding inspection in steel structures for GDOT.
