RT-1 indicates?

• A. Full RT
• B. Spot RT
• C. After-heat RT
• D. Inspection RT

Answer: (B)

RT-1 is a radiographic testing designation that means spot radiography. In ASME Section V, radiography designations describe how much of the weld or component is examined. Spot radiography focuses on a limited, targeted area with one or a few exposures rather than surveying the entire length. This approach is used when you need to check critical features quickly or when geometry or accessibility makes full coverage impractical, and it typically involves lower exposure and cost while still providing a check on key flaws. The other terms don’t match the standard RT labeling for the extent of the radiographic examination; full radiography would cover more of the weld, and “after-heat” or “inspection” RT aren’t recognized categories in this context.
