What should be included in the tail of a welding symbol?

In the context of welding symbols, the tail of the symbol serves as an area for conveying additional instructions or specifications that are crucial for the welding process. This might include details such as the required welding process, specific filler materials to be used, or any other pertinent notes that do not fit into the standard components of the welding symbol itself.

While information like the thickness of the weld, type of weld, and location are important elements in the symbolism, they are typically represented elsewhere in the welding symbol (notably on the arrow side or across the symbol itself). The tail allows for flexibility and clarity when unique instructions are necessary for that particular weld. This ensures that a welder or fabricator has all the relevant information needed to complete the work as specified. Thus, including additional instructions or specifications in the tail is essential for proper communication and execution of welding tasks.
