I suspect a technique issue. It may be as simple as you created mill scale on the backside and when you went to weld it you did not compensate for it. I find more heat faster, and getting some rod in right away for the "cleaning effect" works.
I welded some heavily mill scaled flat stock to solid square stock that didn't have the mill scale removed because it would ruin the "rustic look."
I used 200+ amps and 3/32" rod. I went immediate full pedal to puddle quick and got rod in immediately - it all welded real nice and no grinder marks.
