: The study of how metals transition from liquid to solid states and how chemical compositions affect weldability and crack sensitivity. Weld Discontinuities
Improved fluorescent materials and digital cameras enhanced the sensitivity of detecting surface cracks in ferromagnetic materials.
The 2020-2021 period marked a pivotal shift in the industry, driven by Industry 4.0 integration, the need for increased efficiency, and the refinement of NDT (Non-Destructive Testing) techniques. This article explores the key advancements in welding inspection technologies during that era, many of which continue to define the current landscape of quality assurance. 1.

Typical inspection workflow (practical sequence)
marks a pivotal era in structural engineering and manufacturing, characterized by the convergence of traditional quality control principles with advanced digital and non-destructive testing (NDT) methodologies. During this timeframe, the American Welding Society (AWS) updated its core educational framework, introducing the AWS WIT-T:2020 Welding Inspection Technology manual and the accompanying WIT-W:2020 Workbook . These publications serve as the authoritative standard for professionals preparing for the Certified Welding Inspector (CWI) exam. They bridge foundational metallurgy with automated inspection systems. This article explores the key advancements in welding
PAUT wasn't new in 2020, but the accessibility of portable, tablet-based PAUT devices exploded. Inspectors could now map weld discontinuities in 3D and share the raw data instantly.
Destructive tests are primarily utilized during the qualification phase of a WPS or PQR to verify the mechanical properties of a weldment:
