Where should a weld be made according to the specification displayed?

The specification indicating where a weld should be made typically uses an arrow to show the specific area of the joint that requires attention. When the instruction specifies "the side opposite the arrow," it indicates that the weld is to be done on that specific side of the joint as per the design requirements outlined in the blueprint.

Welding on the side opposite the arrow ensures compliance with the engineering specifications, which may be designed for strength, accessibility, or appearance. This detail is critical because it aligns the welding process with the structural integrity and requirements defined for the project.

While other options may suggest performing welds in various locations, following the specifications accurately is essential for ensuring that the weld meets the needed design and safety criteria.
