In welding symbol conventions, the surfacing weld symbol is placed on which side of the reference line?

• A. Arrow side
• B. Tail side
• C. Center of line
• D. Either side depending on notation

Answer: (A)

Welding symbols indicate which surface of the joint to weld by where the symbol sits relative to the reference line. Surfacing adds material to the surface, so the symbol for this weld is placed on the arrow side to show that the surface toward the arrow is the one being built up. Putting the symbol on the tail side would mean the opposite surface is being surfaced, which isn’t the standard interpretation for surfacing. The center of the line or choosing either side aren’t the conventions for indicating surfacing; the arrow side is the defined position.
