It is cost-effective, fast, and capable of identifying surface defects like undercuts, cracks, and porosity. 2. Advanced Non-Destructive Testing (NDT) Methods
One of the standout innovations was the for automated in-process and interpass inspection of multipass welds, described in detail in a 2021 publication in IEEE Xplore . This novel probe operates at temperatures up to 350 °C (far beyond the 100 °C limit of conventional probes) and performs angled weld inspection using 55° transverse waves. The wheel probe's endless rotation enables continuous inspection, making it well-suited for integration within automated environments commonly employed for high-integrity multipass welding applications such as in the aerospace, nuclear, and petrochemical sectors. welding inspection technology 2020 pdf 2021
details how to verify that a weld is performed according to qualified parameters. Advanced NDT : The rise of handheld laser welding
Before the pandemic, welding inspection relied heavily on physical presence. Manual Ultrasonic Testing (UT) and Radiographic Testing (RT) with film were the gold standards. However, the need for remote monitoring in 2020 accelerated the adoption of technologies that were previously considered "nice to have" rather than essential.

Note: This review synthesizes trends commonly found in journals such as the NDT & E International, Welding Journal, and conference proceedings from the IIW (International Institute of Welding) during the 2020-2021 timeframe.
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. the transition was not smooth:
Verifying base materials, checking joint geometry, ensuring proper fit-up, and validating Welding Procedure Specifications (WPS) and Procedure Qualification Records (PQR).
The transition from film-based radiography to digital sensors reached a tipping point. Digital radiography allowed for immediate image processing, eliminating the need for chemical developers and significantly shortening the inspection cycle in manufacturing plants. 3. Laser Scanning and 3D Modeling
The year 2020, driven by the need for remote work solutions, accelerated the adoption of digital reporting systems and remote inspection technologies.
Despite advances, the transition was not smooth:
