Surprised E7018 isn't recommended, thought it was a go-to.

E7048-H4 is the right choice for high CE!

I recall something about E7048 being better for hot taps, especially with a CE over 0.42%. I think that’s what I’d go with.

I’m a bit confused. I know E7018 is commonly used, but I feel like it might not be suitable for this situation.

I practiced a similar question, and I believe E7048-H4 is specifically designed for higher CE materials. That might be the right answer.

I think I remember that for higher carbon equivalents, we should be cautious about cracking. E7018 might be a safe choice, but I'm not entirely sure.

Based on the information provided, I believe the correct answer is E7048-H4. The high-hydrogen coating should help manage the higher carbon content.

Hmm, this seems like a tricky one. I'll need to think carefully about the carbon equivalent (CE) and how that relates to the electrode choice.

E7018? More like E7-NOPE! Gotta go with the H4 for that high-carbon steel, my friends.
