How should weld dimensions generally be indicated on a print?

Weld dimensions are typically indicated near the weld symbol on a print because this placement ensures clarity and direct association with the specific welding requirement. The weld symbol itself serves as a guide for the welder, detailing not only the type of weld but also critical information such as size, length, and any specific requirements. By placing dimensions close to the weld symbol, all pertinent information is easily accessible and understood in context, thereby reducing the potential for errors during fabrication.

Using reference lines, while important for indicating the location and orientation of the weld, does not inherently communicate the specific dimensions required for the weld. Likewise, specifying dimensions only in notes could lead to misunderstandings, as they may not be immediately associated with their respective weld symbols. As for not specifying weld dimensions at all, this is not a best practice since it can lead to ambiguity in manufacturing, which must be avoided to ensure the integrity and quality of the welded joints.
