It's possible you're thinking of a specific symbol or context.
To help me understand what you mean, could you please provide more context? For example:
* What is the symbol being used for? (e.g., a weld symbol, a drawing, a specification)
* Where did you see the symbol? (e.g., a blueprint, a textbook, a website)
* What is the surrounding text? (e.g., any other symbols, numbers, or words)
With more information, I can help you understand the meaning of "ANS" in the context of welding society symbols.
