How is a field weld shown on a welding symbol?

• A. A Black Flag/Pennant Pointing Toward The Weld Symbol
• B. A Circle Around The Symbol
• C. A Dashed Line
• D. A Star

Answer: (A)

In welding symbols, telling whether a weld must be done in the field is shown with a flag. A black flag or pennant is placed on the arrow side of the symbol and points toward the weld symbol, signaling that the weld is to be performed at the job site rather than in the shop. The other marks have different meanings (for example, a circle around the symbol indicates a weld all around a circumference, not field work; a dashed line or a star isn’t used to indicate field welding), so the flag pointing toward the weld is the specific cue for a field weld.
