Which item must appear on the radiograph?

• A. The operator's certification number
• B. Date and shop order number only
• C. Radiographic ID number, date, and shop order number
• D. The weld size and material grade

Answer: (C)

Radiographs used in welding inspection must be identifiable so they can be traced back to the exact weld and its records. The best practice is to include a radiographic identification number, the date the exposure was made, and the shop order number on the film. This combination guarantees that every film can be uniquely linked to a specific weld or job, when it was done, and which project it belongs to. The operator’s certification number isn’t required on the radiograph itself for traceability, and weld size or material grade belong in the fabrication documentation rather than on the radiograph.
