What do the terms 'arrow side' and 'other side' mean?

• A. The side to which the arrow points is the arrow side. The opposite side of the joint is the other side.
• B. The side with the arrowhead is the arrow side.
• C. The left side is the arrow side.
• D. The terms refer to the orientation of the welding procedure.

Answer: (A)

In welding symbols, the arrow points to the side of the joint that will be welded, and that side is called the arrow side. The opposite face is simply the other side. This convention helps the welder know exactly where to apply the weld from the drawing, especially when a joint has welds on one side or both.

The side being defined is not determined by which end of the arrow has the head, nor by a fixed left-right orientation or by any statement about the welding procedure itself. The correct interpretation is that the arrow designates the side to be welded, and the other side is the remaining face.
