: This is the core reference for weld inspection, covering safety (ventilation, electric shock), cutting processes (Oxyfuel, Plasma Arc), and metal properties. AWS WIT-T:2020 Welding Inspection Technology
With reduced on-site personnel in 2020, crawlers and robotic scanners (e.g., Inuktun, Eddyfi) equipped with UT or EC sensors became essential. These systems could map weld corrosion and cracks remotely. A (PDF) described a robotic PAUT system inspecting 2 km of pipeline without a single inspector inside the trench. welding inspection technology 2020 pdf 2021

The result: Inspection time reduced by 40% compared to 2019 baseline, with zero human contact on-site. The procedures for this project are detailed in several technical papers from the Journal of NDT (2021, Vol 39, Issue 2).
Perhaps the most significant advance was the development of systems capable of inspecting welds , rather than after completion. Traditional practice inspected welds only after all passes were complete and after an appropriate cooling period. This delay between defect formation and discovery meant that entire components could be rendered scrap before a flaw was detected. The 2020–2021 period saw the successful deployment of systems that offer early defect detection, drastically reducing this delay and enabling in-process weld repair, leading to higher production efficiency, reduced rework rates, and lower production costs.

This article explores the core advancements, methodologies, and standards that defined welding inspection technology during the 2020–2021 period, offering a comprehensive reference guide for QA/QC professionals, engineers, and students seeking foundational insights often found in comprehensive PDF manuals from this era. 1. The 2020–2021 Paradigm Shift in Welding Inspection
The 2020–2021 period saw several inspection technologies mature or become mainstream, documented in contemporaneous PDF technical papers and manufacturer datasheets.
It is cost-effective, fast, and capable of identifying surface defects like undercuts, cracks, and porosity. 2. Advanced Non-Destructive Testing (NDT) Methods These systems could map weld corrosion and cracks remotely
