Wow.

The tough thing is about union hall certs is, you have to do things the way they do them, or alot of time they will kinda thumb their noses up at you.

On the landings, when I was in the UA, I was taught to use a 1/16 Landing(they called it a razerblade landing), formed almost like a j-bevel, and 1/16 or no gap.

In my experience with the overhead pipe welding, turning the heat up on the overhead section always helped me out alot.

I know it's not much, but I hope it helps a little bit.

Is this UA weld test using API downhill?
