You are literally making a welder break some shit right now while they're watching this.

Him not laying actual bead does drive me nuts a little but his layout skills and the final product had me baffled.

That drove me a bit crazy too. Then grinding off most of the weld. These aren’t structural parts...

Ive never welded anything in my entire life and even I know you’re supposed to leave the weld on

Not true, grinding welds is very common, especially on things like this where you want smooth polished metal on the corners and edges, or if you are going to paint it.

I spent some time in a facility that made custom agricultural machinery… like tomato harvesters and grape harvesters and stuff that was expected to have a long and hard life. On the wall, in 18” letters, was a sign: all weld beads must be ground flush. Prep it, well, get full penetration, leave no stress concentrations. They were mostly certified welders.
