The tail of a welding symbol typically carries what kind of information?

• A. Welding symbol type
• B. Finish
• C. Material grade
• D. Specification, process, or other reference

Answer: (D)

The tail carries specification, process, or other reference information. In a welding symbol, the main body communicates the weld type, size, location, and any appearance or finish details, while the tail points to the governing document or instruction that controls how the weld is made and inspected. This can be a welding code or standard (for example, AWS or ASME), a Welding Procedure Specification (WPS) reference, or another referenced document. The tail, therefore, tells you which rules apply to this weld, not the basic weld geometry or the material grade, which are shown elsewhere on the drawing.
