Field weld symbols are examples of which broader symbol category?

• A. Supplementary Weld Symbol
• B. Basic Weld Symbol
• C. Reference Symbol
• D. Dimension Symbol

Answer: (A)

Field welding location is additional information that modifies how the weld is to be applied, not the shape of the weld itself. Basic weld symbols specify the type of weld (like fillet or groove), while supplementary weld symbols add details such as where the weld will be made, how it should be finished, or other qualifiers. Since a field weld is about performing the weld at the job site rather than in a shop, it fits under supplementary symbols. The other categories describe the weld form (basic symbol), notes or references (reference symbol), or measurements (dimension symbol), which is why they don’t apply here.
