NDT allows inspectors to evaluate the quality of a production weld without damaging the final component.

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

Post‑weld visual inspection (VT): dimensional checks, surface discontinuities, weld profile.

If you are studying welding inspection or updating your company’s QA manual, the are essential reading because they document the pivot from analog to digital. They bridge the gap between old-school NDT and the AI-driven tools we are seeing in 2024 and beyond. welding inspection technology 2020 pdf 2021

TOFD gained traction for crack sizing in thick welds, especially in pressure vessels and storage tanks. The method’s accuracy (±1 mm) and reproducibility made it a favorite for fitness-for-service assessments during 2021 refinery turnarounds.

Before 2020, Industry 4.0 was a buzzword. By mid-2021, it was a necessity.

High-definition pan-tilt-zoom (PTZ) cameras and specialized drones were utilized to inspect welds in hazardous or confined spaces, such as nuclear containment areas or offshore wind turbine pylons. NDT allows inspectors to evaluate the quality of

Note: Always refer to the latest editions of codes and standards. This write-up reflects technology as documented in 2020–2021.

Released mid-2021, this standard harmonized acceptance levels across VT, PT, MT, UT, and RT. The key update was the alignment of UT acceptance criteria with RT (making PAUT a true substitute).

Handheld laser scanners became prevalent for surface inspections. These devices create a 3D digital twin of the weld bead, measuring crown height, undercut, and width against CAD specifications in real-time. Impact on Standards and Safety If you are studying welding inspection or updating

Environmental regulations and the need for immediate feedback accelerated the decline of film-based radiography. 2020 manuals emphasized Computed Radiography (using storage phosphor plates) and Direct Digital Radiography (using flat-panel detectors).

Technical documentation and compliance guidelines evolved in tandem with these technological updates. Standard-developing organizations adapted their codes to accommodate digital workflows. Adaptations in Major Codes (AWS & ASME)

It provides real-time, cross-sectional views of the weld internal structure.
