1.3 Automated and Robotic Weld Inspection

With social distancing protocols, automated crawlers for tank and pipeline welding inspections gained traction. The typical welding inspection technology 2020 pdf 2021 whitepapers discussed:

• Magnetic wheel crawlers with PAUT and TOFD (Time-of-Flight Diffraction).
• Drone-based visual inspection of elevated structures.
• Laser profilometry for weld cap geometry.

10. Conclusion

2020–2021 saw accelerated digitalization of welding inspection, wider adoption of PAUT/TOFD and DR, early use of AI for VT, and growing interest in automation—driven by efficiency, safety, and traceability needs. Successful adoption requires investment in equipment, training, data management, and validation against accepted codes. welding inspection technology 2020 pdf 2021

Part 7: How to Use the "2020–2021" PDFs Today

Even in 2026, these documents remain valuable for three reasons: Magnetic wheel crawlers with PAUT and TOFD (Time-of-Flight

1. Legacy projects: Many bridges, pressure vessels, and pipelines built in 2020-2021 were inspected under these specific rules. If you are maintaining that asset, you need the original inspection criteria.
2. Technology transition: The 2020-2021 docs explain why the industry abandoned film radiography, which helps justify capital expenditure on modern PAUT.
3. Grandfathering: Some codes allow equipment qualified in 2020 to remain in service. The PDFs serve as legal evidence of initial qualification.
