A landmark 2021 review demonstrated the application of deep learning to detect defects in newly created welds with minimal defect sizes, using field-quality manually produced welds rather than pristine laboratory specimens. The research addressed industry standards for defect classification and showed that continuous, digitized monitoring is essential for modern manufacturing and the sustainment of aging infrastructure. A separate study in NDT & E International (Vol. 120, 2021) proposed an automatic welding defect location algorithm based on an improved U‑net network, achieving better performance without any prior knowledge.

This evolution was also captured in major industry publications. The American Welding Society (AWS) published its updated "Welding Inspection Technology" course materials (WIT-T:2020, WIT-W:2020), while the API issued a new edition of its inspection guide, API RP 577:2020. New standards were also introduced, such as the ASTM E2700-20 for phased array ultrasonic testing and ISO 10675-1:2021 for radiographic acceptance levels, providing a formal framework for implementing advanced methods.

For today’s welding engineer, inspector, or QA manager, possessing the right PDFs from this era is not about nostalgia—it is about maintaining compliance, understanding legacy systems, and building a foundation for the next generation of autonomous weld inspection. welding inspection technology 2020 pdf 2021

Expose internal flaws like slag inclusions or porosity by fracturing the specimen directly through the weld.

"Welding Inspection Technology" primarily refers to the official study guide published by the American Welding Society (AWS) for those preparing for the Certified Welding Inspector (CWI) American Welding Society A landmark 2021 review demonstrated the application of

Air-coupled ultrasound represented an even more radical departure from contact methods. A 2021 study in China Welding discussed the possibility of evaluating laser welding seam quality using Lamb wave modes in an air-coupled configuration. By eliminating the need for a couplant (gel or water), air-coupled ultrasound enables inspection of moisture-sensitive materials and high-temperature surfaces immediately after welding.

With the increase in digital data from X-ray and Ultrasound, manufacturers faced a bottleneck in interpretation. software, powered by AI and machine learning, began interpreting complex inspection data in real-time, reducing human error and fatigue. Cloud Data Management 120, 2021) proposed an automatic welding defect location

Engineers, certified welding inspectors (CWIs), and quality control managers found themselves searching for digital resources that could bridge the gap between traditional code books (like AWS D1.1 and ASME Section IX) and modern, data-driven inspection techniques. This article provides a comprehensive overview of the welding inspection technologies that defined the 2020–2021 period, highlights critical PDF resources, and explains how these documents remain relevant for today’s fabrication, construction, and pipeline industries.
