: Identifying flaws such as porosity, inclusions, undercut, and lack of fusion, and determining when a "discontinuity" becomes a "defect" based on specific codes. Visual Inspection (VT)
Reduced radiation via DR, use of robotic crawlers and drones Highly dependent on individual inspector interpretation Enhanced by Automated Flaw Recognition (AFR) software Conclusion

: Often considered the most important NDT (Non-Destructive Testing) method, focusing on inspection before, during, and after welding. Other NDT Methods
Software developers introduced AI algorithms capable of pre-screening radiographic and ultrasonic data. By training models on thousands of historical weld defect profiles, these systems flagged potential anomalies, reducing the cognitive fatigue of human inspectors. | Document Title | Organization | Year |
The need for social distancing and reduced site travel during the pandemic accelerated the use of high-resolution cameras and smart glasses for remote inspections. Go to product viewer dialog for this item. Welding Inspection Technology, Published by AWS, 2020-01-01

PAUT became the preferred replacement for RT in many pipeline and structural applications. By 2020, portable PAUT units (e.g., Olympus OmniScan X3, Zetec Topaz) were common. The key advantage: no radiation, instant results, and full data recording. highlighted PAUT’s role in offshore wind fabrication, where rapid inspection of thick-section welds was critical.
Labor shortages and strict safety protocols in 2020 and 2021 drove rapid adoption of automated and remote inspection hardware. Unmanned Inspection Crawlers
