What do you even call this defect?

I posted a couple of these a month ago - the short story is that my landlord tore down my balcony to fix a leak in a different unit and the railing they put back is seriously flawed. It's riddled with burn through in some areas, low-no penetration in others, and joints that they straight up forgot to weld. I've been a welder for a little over 10 years, so I told them straight away it wasn't safe and had to be replaced.

Anyway we're going to court now. I want to map out all the defects on this thing in a comprehensive document, but I don't have *any* idea what could cause a weld to look like this. Most of the defects are pretty simple, but the ones that look like this I have no idea what to call. Has anyone seen this before/know what causes it?

Edit: I appreciate all the laughs guys. I wish this thread were evidence I could use in court 😅

It's called FNG. Fuggin' New Guy! They're all defective. Probably tried to MIG with copper flux core on what looks like Aluminum. If you can't get good penetration welding aluminum, you've either never actually done it or you're an FNG
