Which of the following welds does not require welder's identification?

• A. All welds require identification
• B. Vertical welded joints within the final shell course
• C. Roof plate welds and flanges-to-Nozzle-neck welds
• D. Roof plate welds and bottom plate welds

Answer: (C)

The correct response is based on the requirements specified in the API 653 standards and the intentions behind weld identification. In certain circumstances, particularly in aboveground storage tanks, not all welds necessitate a welder's identification. Specifically, roof plate welds and flanges-to-nozzle-neck welds are examples where the requirement for a specific welder’s identification is not always mandated. Roof plate welds are typically part of the overall structure that does not come under stringent requirement for individual welder traceability, particularly if the quality assurance has been ensured through other means. Similarly, flanges-to-nozzle-neck welds may also be considered under certain regulations and practices where the identification of the welder is less critical due to the nature of their function and the overall quality control processes in place. The rationale for not requiring identification for these welds might stem from the fact that the welds are often completed in a controlled environment with multiple processes in place to ensure the integrity of the work, which diminishes the need for tracking the performance of individual welders for each specific weld type in that context. In contrast, other options either imply a universal requirement or point to welds that fall under stricter quality assurance protocols necessitating identification, thus setting those
