Hi, I'm teaching myself stick welding. In this photo I made a flare bevel weld between some 11 gauge rectangle tubes using 3/32" 6011 electrodes at 80A DCEP. I think the "stack of dimes" appearance looks ok, not great, but what worries me is there's something that looks like maybe scalding or porosity along the edges of the weld. What is this, is it a problem, and if so how can I correct it?

Thanks,
