What type of symbol denotes that a weld is to be completed in the field?

• A. A secondary welding symbol
• B. A welding symbol
• C. A basic welding symbol
• D. A supplementary symbol

Answer: (D)

In welding symbol notation, the information added to a basic weld symbol to convey extra requirements is provided by supplementary symbols. The field-weld requirement is one of these additions, signaling that the weld must be completed at the job site rather than in the shop. That’s why the correct choice is a supplementary symbol: it’s specifically used to modify the basic weld symbol with on-site installation details. The other categories describe the fundamental weld type or the overall symbol, not the on-site location, so they don’t convey the field-work requirement on their own. In practice, indicating a field weld helps ensure proper planning for access, handling, and inspection.
