Which AWS publication contains requirements for welding symbols?

Explanation:
Welding symbols are the standardized language used on drawings to describe how a weld should be made, where it goes, and any special details like size or finish. The AWS publication that codifies this symbol system is AWS A2.4, Standard Welding Symbols. It lays out how the symbol is built—the basic weld shape, any supplementary symbols, sizes, and finishes—and how to position it on a drawing so the weld is understood on the correct side of the joint. It also explains how to use a tail to convey welding processes or additional instructions and how to read multiple welds along a joint. Other AWS publications cover welding processes, terminology, or structural requirements, but they do not establish the welding symbol conventions themselves.
