Abstract: The accurate detection and classification of invisible weld defects is very important to ensure the quality of welding products. A magneto-optical (MO) imaging detection system excited by a ...

Abstract: Non-destructive testing of weld based on radiographic images is crucial for quality control of spiral steel pipes. However, accurately discriminating defect images from high-resolution and ...

Introduction: Accurate defect detection in dissimilar metal welds (DMWs) remains a major challenge due to heterogeneous microstructures and imaging noise. Methods: In this study, we propose a novel ...
