Expanding permissions for using PAUT in place of traditional radiography for pressure vessel fabrication.

Widely utilized in Europe, the UK, and international oil and gas projects, offering structured steps from Visual Welding Inspector (3.0) to Senior Welding Inspector (3.2).

When visual inspection is not enough to guarantee internal quality, inspectors rely on various engineering technologies to look inside or on the surface of a weld without destroying it. NDT Method Target Areas Best Used For Pros / Cons All visible surface discontinuities, undercut, profiles. Cheap, fast / Surface only. Liquid Penetrant (PT) Clean, non-porous materials; surface-breaking cracks. Highly portable / No subsurface detection. Magnetic Particle (MT) Surface / Subsurface Ferromagnetic materials; surface and near-surface cracks. Fast results / Limited to magnetic metals. Ultrasonic Testing (UT) Volumetric (Internal) Subsurface flaws, laminations, precise depth tracking. Highly accurate / Requires high operator skill. Radiographic Testing (RT) Volumetric (Internal)

Ultimately, 2020 was the year welding inspection began to break free from its traditional reactive mold. The technologies documented in the PDFs and research papers of that year—from the foundational texts to robotics and AI—painted a clear picture of a future characterized by autonomous systems and an unwavering commitment to safety and quality.

Preventing costly production downtime by catching defects early in the production cycle.

The most comprehensive educational resource for welding inspectors published in 2020 was the sixth edition of AWS Welding Inspection Technology (WIT). Available in both print (ISBN 978-1-64322-095-6) and PDF (ISBN 978-1-64322-096-3) formats, this 2020 publication covers the complete spectrum of welding inspection knowledge, from certification requirements and safe practices to metal joining processes, cutting processes, weld joint geometry, welding symbols, and NDT methods. The handbook serves as the primary reference for AWS Certified Welding Inspector (CWI) examination preparation and ongoing professional development. NDT Method Target Areas Best Used For Pros

To tackle challenges like high-temperature operation and adapting to an evolving weld profile, researchers at the University of Strathclyde pioneered a using 64-element phased arrays and high-temperature wedges to generate sector scans after each weld pass. Crucially, they also introduced the concept of in-process calibration using a second duplication sample with intentionally embedded tungsten inclusions , which could more reliably identify subtle defects than conventional methods.

Radiographic testing remains one of the most widely used volumetric NDT methods for detecting internal weld defects such as porosity, slag inclusions, and incomplete fusion. In 2020, digital radiography (DR) emerged as a significant improvement over traditional film-based radiography, offering faster image acquisition, lower radiation exposure, and enhanced digital image processing capabilities. DR systems convert X-ray radiation directly into digital signals, enabling real-time image viewing and automated defect recognition algorithms.

The year 2020 marked a significant turning point for welding inspection technology, witnessing the widespread adoption of advanced non-destructive testing (NDT) methods, the initial integration of artificial intelligence into quality assurance workflows, and the publication of several critical industry standards. These developments came in direct response to the increasing complexity of industrial fabrication, particularly in sectors such as shipbuilding, aerospace, and pressure vessel manufacturing, where weld integrity is directly linked to operational safety and structural reliability. This article examines the defining technologies, standards, and methodologies that shaped welding inspection in 2020, serving as a practical resource for professionals seeking authoritative reference materials in PDF format.
