Actually it was 6010 downhill and hippie filler and cap, hippie is now all but gone due to not having asbestos in the flux anymore, leading to xray and failure problems, now replaced by 8010.

For everyone elses info, no cross country pipeline in America was ever welded with 7018.

We are getting a little off the beaten path here, however alot of practices in welding have been changed, but that doens't change the fact that equipment in service is grandfathered. Case in point, weave beads. No longer allowed in Coded Vessles or Pressurized pipelines, millions of them in service with no problems though.

 

Yes, strayed from the original path just a teeny bit

Ok, I got a few "6013 should be fine, grind it out and do it gain if you think you got little penetration." 7018 is for capping, but then some say it's not necessary.

According to the chart, 6010/11 and 6013 are the same strength. . .one for diggin through crap and one not. Since this is all clean, freshly ground new steel I think I will stick with 6013. Then reinforce corner and stress areas with 7018?

A lot of my worry is in the design of this stupid thing. Just way too many stressed joints now that I see it going together. I think I might try it again with more HSS tube instead of plate Or screw it, just go with radius arms and coils

Appreciate yalls help

 

Ok, everybody has pulled out their welding card. Great. If you welded it correctly you are fine. If you think the weld is suspect, fish plate it. Especially on a vert up joint. It will leave you with much more surface area of weld in the horizontal position than the verticle up. Which is much easier for a beginner to weld.

One thing I can tell you is finishing a verticle up joint, leaves the puddle at the end of a joint. The puddle at the end of the weld is traditionally the weakest part of the weld. Just make sure it is filled up past flush even if you have to allow it to cool and chip it and hit it again.

 

Wow everyone went way outside on this one. I cant tell you what rods are used on pipe lines or which x-rays out with what. I think mrxlh is correct in his post. If you weld it correctly and pay attention to what you are doing you should be fine. There has been a lot of good info on this post. The biggest thing is keep it clean and use correct technique you should get good penetration and a solid weld. If you doubt it being correct, its probably not, grind it out and do it again or reinforce it.

 

You will fine with 60 series rod, the base metal has the lower tensile strengh as stated the the rod.
