Chapter 8: Safety in Inspection (OSHA 1910.252)
- Radiation (RT): Controlled area. Dosimeter badge required. No entry if survey meter > 2 mR/hr.
- Electrical (MT): Yoke grounding check before use.
- Confined Space: Gas meter (O2 19.5-23.5%, LEL <10%, CO <25 ppm).
- UV Light (PT/MT): Skin/eye protection (polycarbonate face shield).
A. Advanced Ultrasonic Testing (PAUT and TOFD)
In 2020, Phased Array Ultrasonic Testing (PAUT) solidified its position as the preferred method for inspecting critical welds, particularly in the oil & gas and pipeline sectors. welding inspection technology 2020 pdf
- High-Speed Inspection: Modern PAUT systems allowed for the inspection of welds at speeds significantly faster than traditional Radiographic Testing (RT), without the safety hazards associated with ionizing radiation.
- Data Visualization: Improved software interfaces allowed inspectors to visualize cross-sections of welds in real-time, offering immediate determination of defect size and orientation.
6. Challenges Facing the Industry (2020)
- Skills Gap: While technology advanced, the industry faced a shortage of qualified technicians capable of interpreting complex data from PAUT and DR systems.
- Cost of Transition: Small and medium enterprises (SMEs) struggled with the high initial capital investment required to switch from analog (film/magnetic particle) to digital/automated systems.
- Connectivity: Remote inspection relied heavily on internet connectivity, which remained a challenge for inspection sites in remote locations (e.g., deep-sea platforms or desert pipelines).
C. ASNT NDT Handbook – Vol. 10 (2020 Digital Release)
For the first time, ASNT released a fully interactive PDF of the NDT handbook in 2020, focusing on signal processing and machine learning in weld inspection. Since I cannot directly attach a downloadable PDF
