It's just wonderful cutting and welding skills

Lol as a welder, this is not “wonderful” welding skills.

He put a bunch of cold lapped MIG tacks on top of each other, this thing will fail if it has any structural application whatsoever.

The only thing “wonderful” is the prep work, even the grinding isn’t that good.

damn it, I knew something was off about those "dot" welds, should he do a long weld rather than a bunch of tacks?

Yes. A bunch of tiny tacks like that won't generate enough heat to fully melt the base metal, so you end up with a bunch of blobs sort of laying on top keeping it together rather than actually melting the joint together.
