That's blistering on the back of the weld, from too much heat. It should look like the start of the weld where it was colder and you just see the original joint between the two pieces of material. Excess heat is also what causes the longitudinal cracking along the weld. I'd try moving a bit faster and/or reducing the current.BramR wrote:As you look close there is a line in the bead. Is this the residue of the oxide that floated on the penetration?

Guys, it's finished.
The good news is the welds are fine. The bad news is I probably should have used a bigger box profile. For the girls it's fine, for me it's a bit to flexible.
Could be that I'll make another one.
What a learner!!! There are some peppery joints. Mostly I think from my filler rod that got to far from the puddle. Or me trying to fill com a wrong angle.
Had a lot of fun & learned a lot.

I would have buttressed that angle with some 1/4 plate. Don't have my trig table out but hang 100 lb on it and the forces at that weld are likely over 1000 lb.
Stone knives and bearskins.....and a NEW EVERLAST 164SI !!!
That's my newly shared work welder.
At home I got a Power Tig 185 DV. Nice, but no plasma cutting... Nice tight arc after a second.
