I'll start with a broad search to get an overview and then refine to find specific PDFs. search results provide a variety of relevant sources. I'll open several to gather detailed information for the article. search results provide a good amount of information on various aspects. I'll also search for specific topics like "remote visual inspection", "thermography", "eddy current testing", "standards", "training", and "phased array ultrasonic testing" to ensure comprehensive coverage. have a good amount of information to write a comprehensive article. The article will cover key technologies, standards, training, and future trends. I'll structure it with an introduction, sections on core NDT methods, advanced digital techniques, automation and remote inspection, standards, training, and a conclusion. article explores the transformative technologies in welding inspection as documented in key publications from 2020 and 2021. It focuses on the integration of advanced digital methods and automation that have redefined quality assurance standards.
Non-metallic solid material trapped in the weld metal or between the weld and base metal. Ultrasonic Testing (UT) or Radiographic Testing (RT).
: The digital books feature high-resolution graphics. These help inspectors spot tiny weld flaws easily. Top NDT Technologies (2020–2021) welding inspection technology 2020 pdf 2021
The welding inspection landscape underwent a seismic shift between 2020 and 2021. As industries grappled with pandemic-induced supply chain disruptions, remote work mandates, and the accelerating push toward Industry 4.0, the demand for accessible, up-to-date technical documentation—specifically in formats—skyrocketed.

Prioritizes volumetric testing (RT and UT) due to the high pressures and hazardous materials transported through cross-country pipelines and chemical processing vessels.
AI models trained on thousands of historical exposures began pre-screening digital radiographs to flag potential porosity and slag inclusions. search results provide a variety of relevant sources
The most fundamental and cost-effective method. VT requires proper lighting, gauges (such as Cambridge or Hi-Lo gauges), and a trained eye to catch surface discontinuities before they are buried under subsequent weld passes.
Inspection times for complex geometries were reduced by up to 40% through automated scanning.
Active thermography emerged as a complementary tool, with specific PDF guides demonstrating how to document results for ISO 17635 and ISO 3834, and extend workflows to EN 1090 and ASME requirements. An autonomous deep-computing framework presented in 2021 analyzed raw videos from infrared systems to predict weld nugget shape and size in resistance spot welding with unprecedented accuracy and speed, using deep neural networks.
The 2020 update of the manual remains the foundational standard for inspectors. It structures the inspector's responsibilities into three critical phases:
