True or False: The tail of a welding symbol is optional.

• A. True
• B. False
• C. Not applicable
• D. Cannot be determined

Answer: (A)

The tail on a welding symbol is optional and used only when there’s extra information to convey beyond the main symbol. If there are no supplementary requirements (for example, no reference to a welding procedure specification, standards, preheat, post‑weld heat treatment, or other special instructions), the tail isn’t included and the symbol communicates everything needed. So this statement is true: you omit the tail when there’s no additional instruction to record. If additional requirements exist, the tail is added to carry that information. The other options don’t fit because they imply the tail must always be present or provide no usable guidance about when it’s used.
