What does AWS 5.4 cover?

What does AWS 5.4 cover?

• A. SMAW stainless steel electrodes
• B. SMAW carbon steel electrodes
• C. GTAW bare stainless steel filler metals
• D. GMAW stainless steel filler metals

Answer: (A)

The key idea is that AWS 5.4 specifies stainless steel electrodes for the shielded metal arc welding process. This standard defines how stainless SMAW electrodes are classified and what they must meet in terms chemistry, mechanical properties, coating, and intended welding positions. So it directly covers the stainless steel electrodes used with the SMAW method. The other options point to different AWS specifications or different welding processes: carbon steel SMAW electrodes are covered by a separate standard, not 5.4; filler metals for GTAW (TIG) and for other welding methods have their own specifications. In short, AWS 5.4 is the standard you’d consult for stainless steel electrodes used with SMAW.
