I am sure they are going to make this stuff illegal soon. Its high density fun
I was dicking around with just 3/32 6010 and 7016, doing butt welds on 1/4 inch flat plate with a 3/32 gap between the two plates. No bevels, because lazy and noise.
With the 6010 I was able to get a bead on the other side for about 4 inches, before I had to changed my rod and must have changed my angle or speed or method or something after that. 7016 was similar, except it was just below the surface, and a lot slower. It was actually really cool to be able to do the 'same thing' as what all these pipe weldy people are doings. The 6010 looked quite cool, ended up being stacked dimes exactly level with the top, but the bottom bead was just like, I dunno, it looked like a random stringer on the bottom.
The 7016 had fine ripples, flat with the top, but did not poke out the bottom at all.
Also done a quick bend test, on 1.5 inch square 2.0 mm thick sheet welded to 1/4 inch plate in a t-joint... I used 6013 2.0mm, 7016 2.5mm, and 6010 2.5mm and then used a spanner to bend the sheet to try and break the weld, and all of them broke the steel before the weld. The welds did not budge. I was bending the metal it toward the bead on each occasion. I honestly thought the 6013 would flake out, but good on it, it was solid
