Automation transitioned from a luxury to a baseline necessity during the 2020–2021 manufacturing cycle.
The manual is structured into 10 key chapters that cover the foundational knowledge required for professional weld inspection:
While the pandemic dictated operational protocols, the core technology advanced significantly. Technical PDFs and conference proceedings from 2020 and 2021 demonstrate a consolidation of Phased Array Ultrasonic Testing (PAUT) as the preferred method for high-integrity welds. Unlike conventional radiography, which requires safety cordons and film development, PAUT provides immediate results and can be fully digitized.
The developments of 2020-2021 point toward several future trends: welding inspection technology 2020 pdf 2021
Major standards organizations updated code cases during this period to formally accept TFM as an alternative to standard radiography. Digital Radiography (DR) and Computed Radiography (CR)
Inspection profiles could instantly be converted into secure, high-resolution PDFs or DICONDE (Digital Imaging and Communication in Nondestructive Evaluation) files for remote sign-offs by certified welding inspectors (CWIs). Eddy Current Array (ECA) Testing

The primary revolution in 2020-2021 was the introduction of Artificial Intelligence (AI) and Machine Learning (ML), especially Deep Learning, to automate analysis—a crucial step given the complexity of inspection codes and the shortage of qualified inspectors. Key advancements include:
Traditional film radiography began a rapid decline in favor of digital alternatives.
PAUT became the gold standard for weld inspection, surpassing traditional radiography. The 2020–2021 period saw updated code cases allowing PAUT to replace RT in many applications, including pressure vessels and structural steel. Key documents from this era emphasized:
