In a welding symbol, the area referred to by a symbol placed over the reference line indicates which side of the joint?

• A. The area on the arrow side.
• B. The area near the end of the arrow.
• C. The area opposite of the arrow.
• D. A field weld.

Answer: (C)

Welding symbols use the position relative to the reference line to tell you which face of the joint gets the weld. The arrow points to the joint, and the reference line runs along the drawing. When the weld symbol sits above that reference line, it indicates welds on the side opposite the arrow. That single rule lets you read both near and far sides consistently across different joints. So, a symbol over the reference line means welding on the side opposite the arrow. If it were below the line, it would indicate welding on the arrow side. The other idea, like a field weld, is about where the weld is made, not which side of the joint receives it.
