6011 or 7018?

[performance]

Gary,
Disagree on the 6011. If you have DC, 6011 still runs better than 6010. No reason to run 6010 unless a specification calls for it. It's not an AC only rod. It's both, and always has been.
6013 is often classified as medium penetration. It's a great fab rod, and great for GP welding.
7024 will run horizontal.
7018 is often required now for root pass welds, and many places have been replacing 6010 now for insurance reasons.

My run down was not meant to be all inclusive. A lot of rods can run on ac and dc , they just run better on one than the other. I can't even remember the last time I saw 6011 rod on a job site. 7018 is fine for root passes , just not open root passes. On the structural cert with a back up strip they will use 7018 all the way out but on open root its 6010. The last time I used 7024 was many years ago and the horz use I do not remember. If I think 7024 is needed there is usually a flux core mig around to do the job faster but If stick is all you have 7024 can put down a lot of weld in comparison to other rods. just make sure there is no cold cracking from the heat being pulled out too fast on large parts.

are you saying 7018 is used to put a bead in pressure pipe?

If your welding 3/8 to 1/4 steel your going to need some heat!!!
1/8 6011 ain't gonna cut it!!!
I would use 7018 multi-pass
you gonna need to bevel your plates to get more strength.
