The pandemic restrictions of 2020 forced the welding inspection industry to replace paper-based asset management with digital workflows. Mobile Inspection Apps and Electronic Tablets

The benefits of non-contact inspection were particularly evident in the 2020 work on for wire + arc additive manufactured (WAAM) samples, published in Ultrasonics . The LU system, comprising a pulsed laser and a laser interferometer, achieved non-contact inspection of artificial defects—cracks, flat-bottom holes, and through-holes—without requiring surface machining. This approach is ideal for additively manufactured components and high-value parts where surface preparation is impractical. Research on finite element simulation of laser-generated ultrasonic waves for quantitative detection of internal weld defects, published in Optik (DOI: 10.1016/j.ijleo.2020.165361), enabled detailed analysis of the interaction between laser-generated Rayleigh waves and internal defects.

By 2021, Phased Array Ultrasonic Testing (PAUT) and Total Focusing Method (TFM) became the gold standards for pipeline and pressure vessel inspections. Unlike standard UT, TFM provides a much higher resolution image of the weld’s internal structure, allowing for precise sizing of defects. 2. Digital Radiography (DR)

Specific from 2020-2021 comparing NDT techniques. The pandemic restrictions of 2020 forced the welding

By mastering the principles outlined in the 2020/2021 inspection frameworks and combining them with modern NDT technologies, welding inspectors protect public safety while keeping heavy industries moving forward efficiently.

Performing visual inspections, marking defects, overseeing non-destructive testing (NDT), and managing comprehensive quality documentation. Material Geometry and Terminology By 2021, Phased Array Ultrasonic Testing (PAUT) and

Technological advancement is ineffective without regulatory framework support. The 2020 and 2021 editions of major welding codes reflected these technological leaps:

The documentation and regulatory frameworks updated in 2021 emphasized "data integrity." With the rise of digital reports, the focus shifted to ensuring that inspection data could not be tampered with, leading to early discussions about blockchain in NDT certification.

Between 2020 and 2021, NDT technology moved rapidly towards higher-resolution imaging, faster inspection speeds, and digital data management. Advanced Ultrasonic Testing (AUT)
