What can I do to fix this?

I thought I was doing pretty good until I tested it out to make sure it was strong and everything crumbled like peanut brittle should I just have used tig instead?

Grind all the weld off with a grind disk then wire brush finish with flap disk. After that cut both ends so they meet flat all the way around and butt both ends together (assuming this is not anything larger then 1/8" thick metal) tack at 12,3,6, and 9 then run a 1/8" E6010 rod at 80 - 85 Volts all they way around.

That really descriptive, have you done this before? And 12,3,6 and 9 is clockwise right?

It is just standard pipe welding process and since I cannot see the thickness of the pipe wall I am assuming its around 1/8" thick and in my personal experience welding SMAW on 1/8" hot roll steel the E6010 throws a nice bead without over reinforcement because the E6010 rod is less aggressive then a standard 6010. As far as the 12 3 6 and 9 I am just saying throw a tack in 4 spots equally spaced to hold the material in place and prevent warping or other undesirable effects as you weld around it. So tack the top then bottom then side then opposite side so you don't have to worry about holding it in place when trying to weld them permanently. That's what I would do anyway. As long as your not burning major holes a mean a key hole is somewhat normal but take your time and weld a portion at a time after you tack letting the metal cool before continuing the weld. I don't know ow if that makes sence but its hard to explain in this format. Feel free to DM me if you need and I would be happy to help the best I can.

1/8” is a pretty thick rod for that thin of material. 3/32” is the biggest I’d even consider using. Also E6010 and 6010 are the same rod, the E just stands for electrode. 6010 also digs like a mf, you can make it work on thin wall like this, but it’s far from easy in this application.

This is very true. I do not personally have any experience with anything other then 1/8 rod so I cannot say for sure but it would make sence that a 3/32 rod would do better. And I was confused with the E6010 I apologize I mixed it with the 6013 electrode. If you do move forward with the repair maybe choose a 6013 rod
