Which side of a joint is called the 'arrow side' in welding terminology?

• A. The side the arrow points to.
• B. The side opposite the arrow.
• C. The side with the base metal only.
• D. The side without any weld.

Answer: (A)

In welding symbolism, the arrow directs you to the location and face of the joint where the weld is applied. The side the arrow points to is called the arrow side. That is the face of the joint that will receive the weld as indicated by the symbol. The opposite face, if discussed, is just the other side. This convention helps you quickly identify which side to weld when reading drawings.
