Where is the size of a weld indicated on a welding symbol?

The size of a weld is indicated on the left side of the weld symbol. This is an essential aspect of reading welding symbols, as it provides critical information for fabricating and inspecting the weld correctly. The size indicates the required dimensions of the weld, such as its leg length for various types of welds, which directly affects the strength and integrity of the welded joint.

By positioning this information on the left side, it allows welders and fabricators to quickly reference the size required for the weld during their work, ensuring that they meet the design specifications and standards expected for that weld type. This placement is standardized across welding symbols to maintain consistency and clarity within welding documentation. Understanding the structure of welding symbols is vital for effective communication between engineers, inspectors, and welders in the field, ensuring that everyone interprets the requirements accurately.
