What does the suffix M indicate in AWS electrode classifications?

• A. Military
• B. Manganese
• C. Magnesium
• D. Moderate

Answer: (A)

In AWS electrode classifications, the extra letters after the basic class describe special qualifiers or standards the electrode meets. The suffix M specifically signals that the electrode is manufactured to military specifications. This means it’s certified to align with military-grade requirements, which can influence its approved uses, testing, and performance criteria. It’s not about the element content (like manganese or magnesium) or a descriptor like “moderate.”
