Information below the reference line on a welding symbol refers to which side of the weld?

• A. Right
• B. Left
• C. Arrow
• D. Other

Answer: (C)

In a welding symbol, the arrow points to the exact location of the weld, and where the additional information sits relative to the reference line tells you which side of the joint gets welded. Information placed below the reference line corresponds to the side toward which the arrow points—the arrow side. The same symbol placed above the line would indicate the weld on the opposite side. So, when you see details below the reference line, you’re reading the requirements for the weld on the arrow side.
