Which AWS specification designates GTAW bare SS filler metals?

Explanation:
When welding stainless steel with GTAW, you need a filler metal that is approved for stainless and suitable for TIG use. AWS specification A5.9 defines filler metals for stainless steel, including the bare rods commonly used in TIG welding. The other specifications cover different base metal families (for example, carbon steel, other alloy steels), so they don’t designate stainless steel TIG filler metals. So the designation for GTAW bare stainless steel filler metals is A5.9.
