What is the minimum radiography qualification level required for a welding inspector?

The minimum radiography qualification level required for a welding inspector is Level 2. This qualification indicates that the inspector has demonstrated the necessary skills and knowledge to interpret and evaluate radiographic films. A Level 2 inspector can perform visual inspections and has a higher understanding of the radiographic techniques, including the ability to recognize defects and assess weld integrity through radiographic images.

Furthermore, having a Level 2 qualification means the inspector is trained to ensure that the standards for safety and quality are being upheld in welding processes. This qualification aligns with industry standards, thus enabling the welding inspector to effectively contribute to the quality assurance processes in high-pressure boiler operations, where the integrity of welds is crucial for safety and performance.
