Was looking at a post somewhere around here about a member that's having a bit of trouble doing a 2G pipe weld..
Now I have never had to do this at any time as a test but have run into this situation at times so I did a little research and came up with the notion that it has to be done with the pipe "up"..
Not sideways like laying it on a bench..
I was tempted to use the positioner but that's cheating I guess so I just did it on the bench the way it is..
They mention a 3/32" gap and a bevel..
I took my subjects to the small lathe and dressed up the ends and had a go at it..
The pipe was 2 1/4" with a 3/16" wall..
One more post..
