Piling welds on top of welds is good to get a feel for things, but you're gonna need to actively look for proper weld reinforcement/penetration. When you pile bead after bead, the entire part is gonna be too massive and you'll run out of power to make a proper weld bead. In most instances, you want a little bit of a crown, but not when its accompanied with a large weld toe angle, as that is where cracks initiate under large amounts of stress.

Only you can check these things in-person. With MIG it's far too easy to pile on too much metal without ensuring proper weld bead profile/penetration. Polishing/etching is your friend.

So basically I need to make some welds that are spaced apart from each other on a fresh base so I can really see what I'm putting down?

My welding school starts us out on 1/8inch plate 1/16 open root (push and pull) then moves us onto 3/32 gap
