Hey,
I'm working on some 3" schedule 80 carbon at school and im experimenting on different ways to fill and cap this pipe. I've gone from doing (tig all the way out)root, hot, 2-3 3/32 fillers and a weave bead cap, to root, hot one 1/8" filler and either weave cap or 3 bead cap.
It seems that when i did the 1-1/8" filler i got a lot of trash that made its way onto my cap, and seems to be between each step on my cap.
What ways would you suggest on filling and capping this pipe?
