I have about 150 lbs. of 7018 & 40lbs. of 6013. Which rod would be best for welding up some spiders?

i would use the 7018. because it is Stronger.

Be sure to preheat too.

Preheat? Didn't know they should be preheated before welding. Thanks for the tip.

Incase you misunderstood....

Pre-heat the metal, not the rods :p

I have been told to use 308 stainless. I have welded three diffs with it now and it has worked. The stainless rod is used because it is less likely to crack. I have tried 7018 also and I know it works too. I had a freind (professional welder for 7 yrs) weld one diff for me with 7018 and when I took it out months later the welds had cracks in them. Also, I have been able to weld with stainless without preheating and not have the welds crack when it cools. ;)

That is some funny shit, but for high level jobs, all flux coated electrodes need to be kept in a rod oven. Moisture kills...

Yeah, 7018 in particular needs to be kept in the dryer/oven. I believe 5p to be the best rod for that. Awesome penetration. Almost as strong as 70's
