When the weld is to be placed on the arrow side of the joint, where is the weld symbol in the drawing?

1. Below the line.

2. Above the line.

3. In the tail.

4. At the end of the arrow.

The correct answer is: Below the line.

When a weld is to be placed on the arrow side of the joint in technical drawings, the weld symbol is positioned below the reference line. This positioning is a standard convention in welding blueprint interpretation, facilitating clear communication about where the weld is to be applied. The reference line in the symbol layout represents the joint, and the arrow points to the part of the joint where the weld is to be made. When the weld symbol is placed below the reference line, it indicates that the weld is to be executed on the side of the joint that is indicated by the arrow, which in this case is the arrow side. This is an essential aspect of welding symbols that helps ensure accuracy and efficiency in manufacturing processes. The other placements mentioned would indicate different weld positions or may not represent a weld on the arrow side at all, hence clearly establishing why the symbol's position below the line directly correlates with the specified welding location.
