Haixu Li, Liwei Guo

Abstract

Phased array ultrasonic technology demonstrates high maturity and significant potential in internal weld defect detection. Its highresolution imaging and flexible beam control enhance accuracy and efficiency, ensuring reliable welding quality. Improvements in signal
processing and intelligent algorithms continue to boost adaptability to complex weld structures. This technology excels in rapid, clear imaging
and shows strong suitability for intricate weld geometries. Future developments in automated recognition, real-time monitoring, and integration with digital manufacturing will further strengthen its role in weld quality control and critical engineering safety.
