Gas tungsten arc welding (GTAW) stands as a pivotal process within the aerospace industry, a sector known for its stringent demands not only on surface aesthetics but also on internal microstructural integrity and performance. While various non-destructive testing (NDT) methods are employed to scrutinize weld quality, their limitations are evident. Firstly, NDT is typically conducted offline, post-welding, by skilled technicians. Furthermore, it falls short in inspecting every product comprehensively, relying instead on manual sampling inspection. In recent years, as lightweight manufacturing gains precedence and robotic automatic welding advances rapidly, ensuring the high stability and reliability of weld products with zero defects becomes both crucial and complex. This necessitates a paradigm shift towards more robust and efficient inspection methodologies capable of meeting the evolving demands of modern manufacturing.
