Which AWS specification covers SMAW stainless steel electrodes?

Which AWS specification covers SMAW stainless steel electrodes?

• A. A5.4
• B. A5.9
• C. A5.3
• D. A5.1

Answer: (A)

Welding specs organize electrodes by both process and base metal. For stick welding on stainless steel, the appropriate AWS standard is the one dedicated to stainless steel electrodes for SMAW. That specification defines the stainless family of filler metals, including their classifications, acceptable chemical compositions, coating types, and performance, ensuring compatibility with stainless steels during SMAW. The other specifications in the options correspond to different electrode families (for example, carbon steel or other alloys) and do not cover stainless steel SMAW electrodes, so they wouldn’t be the correct reference for this scenario. So, the correct specification for SMAW stainless steel electrodes is AWS A5.4.
