| Abstract: | The development history of ultrasonic guided wave technology is briefly reviewed, and the research status of guided waves in weld defect detection is investigated. From the perspective of the interaction between guided waves and welds and the interaction between guided waves and defects, the development and application of defect detection for welds in plate structures are analyzed. Combining the longitudinal mode, torsional mode, and structural characteristics of guided waves, the development of pipeline defect detection technology is expounded. Finally, it summarizes the opportunities and challenges of current guided wave technology in the detection of weld defects. |
