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.
The 2020–2021 period saw several inspection technologies mature or become mainstream, documented in contemporaneous PDF technical papers and manufacturer datasheets.

Do you need a guide on how to access covering these technologies?
: Flipbooks and online modules for the Welding Inspection Technology series became more widely available in 2021, emphasizing digital content creation and interactive learning. Inspection Standards & Guidelines TOFD gained traction for crack sizing in thick
With lockdowns and social distancing, access to physical libraries, training centers, and on-site mentoring stopped. The industry pivoted to digital:
The following developments redefined quality assurance during this era:
Standard reference guides from 2021 focused heavily on configuring focal laws and interpreting S-scans (sectorial scans) to replace industrial radiography. Full Matrix Capture (FMC) and Total Focusing Method (TFM) are the primary resources for professionals preparing for
The deployment of and Time-of-Flight Diffraction (ToFD) reached new heights. PAUT systems utilized multi-element probes to steer, focus, and scan beams through various angles, providing a color-coded, cross-sectional view of the weld.
: Features in the July 2020 Welding Journal highlighted "smart optical monitoring systems" for the online detection of weld defects.
