the one who you can see really good on the side is actually from were i took a metal scribe, and put a mark on it so i knew were to place it on the bender, the one on the cap is actually from a spot were i had slight undercut, and i din't grind enough down into it, i ran my last stringer fairly hot and abit to sharp of a again burning into the previous stringer, but the CWI said it passed visual so thats good i reckon. as this was just a in-house bend so i din't really care which way the grind marks went, which they say if it runs with the weld it gives it a greater chance to fail. i used a wirewheel to get all the slag out - yea i know thats cheating-
and yea man galvanized is the worst, i used to work for great dane trailers building reefers, and we ran galv pipes through the fifth wheel, would litterally have to hold your breath as you welded it.
We got a instructor here who also happens to be a CWI - certified welding inspector, he told me to go ahead and do my 3/8 and 1" plates and send them off to a AWS testing facility to get the paperwork for em.
the one here is a uphill MIG bend, and as you can see i'm rather lazy when it comes to polishing up before bending.

In about a week or two i will have another photo for you guys to see we are going to lay down multi-pass flat welds, then lay horizon, vert, then overhead over them, cut it in half and see how the welds stack going out, kinda like if you think of the earths core and all its layers, i'm really excited about that one, as it will show me what position is my weakest, and what needs to be improved on.
Your plates look good.
Did I see some pin holes from the side view?
Bend test is good for structural stuff next is radiography where nothing can hide!
Good luck.
1976, vocational school, did my first 7018 bend test.
Worked as a welder for 4 years then went in the Navy. 2 years structural steel, 2 years tanks and other stuff (Boiler makers union shop).
Kept getting laid off every winter.
I imagine things are much better now but back in the day we rarely used hearing protection (Even grinding!) and the only forced ventilation I ever saw was in school (how about breathing that green smoke from welding galvanized steel!).
I have a Miller bobcat for sticking things together and still make things. Can I pass a 3/8 plate vertical up, overhead or 45 degree pipe test today, not so much.
