On a welding symbol, where are notes typically placed?

• A. Within the tail
• B. Along the main line
• C. Above the symbol
• D. Near the arrow

Answer: (A)

Notes on a welding symbol are placed in the tail. The tail holds supplementary instructions and references that apply to the weld but aren’t part of the basic weld geometry. This is where you’d indicate the welding process, filler metal, preheat or interpass requirements, or references to a welding procedure specification. The main line and arrow convey the type, size, and location of the weld, while the tail carries the extra instructions. For example, a note in the tail might say “Interpass temperature not to exceed 150°C” or “Weld per AWS D1.1, use E7018.” Other areas of the symbol—the main line or near the arrow—are reserved for the weld type and location, not additional instructions.
