Title: Advancing material characterization damage with ultrasonic testing
Authors: Vu Doan Anh Minh 
Keywords: Ultrasonic testing;Material characterization
Issue Date: 2023
Abstract: 
Non-destructive testing (NDT) has become an essential tool in assessing materials and products without causing alterations. This thesis focuses on the challenges associated with utilizing ultrasonic testing on curved seamless steel pipes, particularly in detecting surface deflections. The research addresses the limitations of the fixed gate positioning method and proposes an innovative solution by utilizing the IF START function. Enhancing defect detection processes for industrial applications, ultimately increasing product quality and reducing rejection rates is this thesis's goal. Examining the implications of varying pipe curvatures on gate positioning and the confusion between interface and deflect detecting gates forms a core aspect of this research. This study seeks to eliminate inaccurate results by exploring the potential of the IF START function to automatically align the deflect detecting gate with the interface gate. Real-life experiments with curved steel pipes will be conducted to validate the proposed solution's effectiveness, aiming to optimize defect detection through gate adjustment based on the interface echo's position
