In the CSA FCAW electrode classification E492T-G, what does the G stand for?

In the CSA FCAW electrode classification E492T-G, what does the G stand for?

• A. Gas Shielded
• B. General Classification for Electrodes Not Covered Under Any Other Classification
• C. For Use on Class G Secondary Containment Vessels for Nuclear Service
• D. General Purpose Electrode for Use on Carbon and Low-Alloy Steels

Answer: (B)

In CSA FCAW electrode classifications, the letters after the numeric strength and form indicate extra attributes of the electrode. The G at the end is a general classification tag used when the electrode doesn’t fit into another specific CSA category. It does not mean gas shielding or any nuclear-related use. So E492T-G specifically communicates a general classification for electrodes not covered under any other classification.
