A much closer look. Ugly welds on the backside where they're not visible are stick -- ugly, but good penetration. Pretty welds on the outside where they'll be cleanly visible are MIG, but my little box isn't hot enough for single pass full penetration welds on 1/4" and 5/16" material like this. This thing's drastically overwelded anyway, so the outside welds here are really cosmetic.
