What connects the reference line to the joint that is to be welded?

Explanation:
In welding symbols, the reference line carries the details of the weld, and the exact joint is identified by an arrow. The arrow extends from the symbol to the joint location, making the link between the reference line and the place where the weld is required. The tail holds extra notes, and finish refers to surface treatment, but neither connects the symbol to the joint. So the connecting element is the arrow.
