Nice looking weld Gary.

Is this a joke? It's one student trying to help another out. If only I had the capabilities of contributing as much as you to this thread.

Appreciate the help everyone! On a 2 inch 6g test do most do cover passes in quarters or do u guys do 1/2 the pipe? I'm welding it in quarters.

I do about halfway on my easy side and then try to go over 1/4 on my hard side. Leaving me room to reposition so I can finish up the side and just over the top. Try to offset your start/stop points from one stringer to the next.

Is the 6g test with 5/32 6010 root and 3/16 8010 fill and cap? All down hill? What is the best height to practice with? 4 or 5 foot off the ground or does it matter? I was going to get some 6 inch schedule 80 to practice. How much gap? How big a bevel? Sorry for all the basic questions, never been to welding school, but did a lot of single pass 1/8 7018 before. I did pretty good with vert up and overhead. Plan to take the 6g test soon. Lot of good info on this forum. Just getting started with it. Thanks in advanced for any advice from the pros.

The context tells me this was most likely 1/8" 6010 root, and 3/32" 7018 out. This is small-bore training & testing for pressure pipe, not pipeline stuff.

Pause where your puddle is about 1/16 over the top line, add a generous amount of filler, and swivel down quickly with the understanding that the middle and bottom will take care of themselves. While you're paused, you should be able to see the metal adequately fill the top. You're only allowed 1/32 of undercut on most weld tests, which is about as much as a fingernail.

I know you said that you had the root down, but understand that you're only allowed up to 1/8 extension and 1/16 recess. They are usually pretty strict and won't even allow you to continue the weld if the root is within parameters.

This is a 6G pipe I did recently. You can get it to cooperate if you get that dip and swivel down. Same thing applies if you stack beads as well. Just wanted to show you an example.

Good luck Gary.

Now, that's a nice cap. what diameter is the pipe?
