Which component of a welding symbol carries information about the welding process to be used?

Which component of a welding symbol carries information about the welding process to be used?

• A. In the tail
• B. In the head
• C. In the dimension line
• D. In the note

Answer: (A)

The welding process to be used is specified in the tail of the welding symbol. The tail is the part reserved for supplementary or controlling information, including the welding process (such as SMAW, GMAW, GTAW) and any related references like the welding procedure specification (WPS). This keeps the geometry and size information—the weld type shown in the main symbol and the dimensions shown on the dimension line—separate from the procedural requirements. Notes may add extra instructions, but the process itself is carried in the tail, making it the best place to convey how the weld is to be performed.
