On which side of the reference line does the surfacing symbol appear?

• A. The arrow side
• B. The tail side
• C. Centered on the line
• D. On the opposite side of the line

Answer: (A)

When reading welding symbols, the side of the reference line where the symbol appears tells you which face of the joint to weld. For a surfacing weld, the symbol is placed on the arrow side, meaning the buildup is done on the side the arrow points to. If it appeared on the tail side, it would indicate the opposite face, and centering on the line doesn’t specify a single-side surfacing in this convention. So the surfacing symbol appearing on the arrow side is the correct interpretation.
