Covers welding geometry, symbols, metallurgy, destructive testing, surface NDT methods, and visual inspection criteria.
The future of welding inspection technology looks promising, with ongoing research and development focused on: The future of welding inspection technology looks promising,
The years 2020 and 2021 served as a critical nexus for welding inspection technology. Prior to this era, the industry relied heavily on manual Non-Destructive Testing (NDT) techniques, which required significant on-site personnel and manual record-keeping. However, operational restrictions during this time catalyzed the adoption of remote, digitized, and highly accurate inspection systems.

Beyond ultrasound, researchers explored other novel approaches. One study successfully combined for comprehensive weld quality formation inspection. Another investigated the use of photodiodes to detect variations in part-to-part gap and weld penetration depth during remote laser welding, particularly for battery tab connectors—a critical application in the burgeoning electric vehicle industry.
