Fun! Love me a bit of stick welding thick section. Interesting to see a sequence, so used to seeing it then doing a drawing, might have to start adding photos..

Looking good though. Just practice?

Looks good.

Any reason you added that 5th cap bead? Its hard to tell from the photos but it looked like you were done capping after the 4th.

Im having trouble now with using 1/8 rod on 3g so having to adjust to 3/32 rod to do all tests as whatever rods you first use according to the common arc testers you have to use thru the whole test. So now trying to find gaps to use smaller than 1/4 to allow easier fill on each test piece

Can you just stick em in a bandsaw and cut the welds out, leaving two more pieces to test with? I do that with thin aluminum sheet I practice on, stick it in the shear and chop the welds out and I"m back welding it again.

I use a grinder with cutting blade to cut each coupon in two as well as backing strips allowing me to get two runs per coupon

We do a 2G in heavy plate for D15.1 but are required to place a stop-start in the middle of the root pass.

Its always a fine line between filling the groove and excessive reinforcement.

The worst part for me is getting impatient to start the next stringer then my work gets too hot.

Cheers, Alan
