Had a good night tonight, second full pipe Ive welded. my tie in's need some work and I didnt even take a pic of the cover passes. I was at 68 amps with 6010 5P+ for the root and 75 amps for the hot pass. and 80 amps with 11018 for the covers since thats what we had, I would much rather has regular good old 7018 but....

I havn't done pipe since school. I had 6010 roots down to an art. Now, I probably couldn't do a root worth a...
When you get out of school, get a job where you use it. Keep practicing. I used to feather my stop/starts and it made all the difference.

For caps on horz pipe welds...there's a technique called the Texas weave...The way you do It Is weave on a 45 degree angle like this------->//////////////...Only on a 45...try it someday...the trick is to have no undercut

viola thats a very good effort at whats probably the hardest position to get right, if thats only your second root on 2g you wont take long to perfect it.as regards your cap, i would concentrate on stringers for now,as gearjam suggests you can weave on 2g but this is very difficult, its only a personal opinion but this is hard on 6g, its a bloody nightmare on 2g, even if you opt for a double weave.good luck in your pipe career . pipefitter

I never heard it called that gearjam but I use it. I figured it out on my own. If you are doing that well already violated then you will get it and soon. Listen to pipefitter as everything he said is true. I don't use a weave at all on code work anymore. Strictly stringers due to less chance of mistakes.
