This was the standout trend of 2020–2021. The sheer volume of data generated by digital PAUT and radiography overwhelmed human reviewers, necessitating AI intervention.
: Standards for protection during welding and cutting operations, such as ANSI Z49.1-2021 .
For surface-breaking defects, MT and PT remained staples, particularly in heavy fabrication. These methods are excellent for finding minute surface cracks that are otherwise missed by the naked eye. D. Eddy Current Testing (ECT) welding inspection technology 2020 pdf 2021
This report summarizes welding inspection technologies, developments, and industry trends during 2020–2021, covering visual inspection, nondestructive testing (NDT) methods, automated and digital inspection systems, standards, and recommendations for adoption.
CT enabled 3D visualization of internal weld structures, allowing inspectors to see exactly how a defect sits within a weld joint. Digital Surface Techniques This was the standout trend of 2020–2021
While visual inspection is crucial, it only detects surface flaws. The 2020-2021 technological landscape was defined by the adoption of advanced NDT techniques to identify subsurface defects. A. Ultrasonic Testing (UT) & Phased Array (PAUT)
The most significant technical strides during this period were in ultrasonic testing. For surface-breaking defects, MT and PT remained staples,
If you want, I can:
The rise of metal 3D printing created a need for new inspection techniques, as traditional weld inspection methods didn’t always detect the unique types of defects associated with laser powder bed fusion. Remote Inspection Technology
