Where is information for the other side placed on a welding symbol?

• A. Above the reference line
• B. Below the reference line
• C. On the tail
• D. At the arrow

Answer: (A)

The information for the side opposite the arrow is placed above the reference line. In a welding symbol, the arrow points to where the weld is located, and data on the arrow side is shown below the reference line, while data for the other (non-arrow) side is shown above it. This layout lets you quickly tell, at a glance, which side of the joint the weld details apply to.
