Which statement correctly describes the meaning of the dashed line in ISO 2553 drawings?

• A. The same side of the joint as the arrowhead point
• B. The opposite end of the weld from the arrowhead
• C. The other side of the joint from where the arrowhead is pointing
• D. The side of the joint to which the arrowhead points

Answer: (C)

In ISO 2553 welding symbols, the arrow points to where the weld is located on the part. The dashed line represents the other side of the joint, i.e., the far face from where the arrowhead is pointing. This convention communicates that there is a weld feature on the opposite side of the joint as viewed, or on the back side, without cluttering the main view with additional solid lines. If the weld were on the same side as the arrowhead, you’d typically see the symbol drawn on that near side without relying on a dashed line. The dashed line therefore indicates the opposite side from the arrow, helping you interpret welds that occur on both faces or on the backside of the joint.
