I'll let you do your own research on the details. But I'll just say that it looks like a big steaming pile until you hit it with a wire brush and not the slag off, then it looks like a proper weld.
YouTube is great for learning.

I have a confession. I used argon shielding gas with my MIG for years. Then I tried resin core and became the world's worse welder (sometimes approximating poor wartime welds adding authenticity but that's not the point). Once I cottoned on to the need to reverse polarity my welding is much better and I'm now a fan of resin core for most basic fabricating. A little splatter perhaps but that can be dealt with.
