What is the purpose of a welding symbol on a print?

The purpose of a welding symbol on a print is to fully specify weld requirements. This includes critical details such as the type of weld, size, length, finishing requirements, and any specific joint preparations. By providing this comprehensive information, welding symbols ensure that welders have clear and precise instructions for creating the welds as intended by the design engineer. This clarity is essential for maintaining structural integrity and ensuring the weld meets safety and quality standards.

Other options may provide useful information related to welding, such as techniques or heat treatments, but they do not capture the holistic role of the welding symbol in conveying all necessary welding specifications.
