i would have thrown that alloy wheel straight in the bin , god knows how many cracks are in it now !
The steel spoke rim up top looks way too badly bent to waste time on;how much tension could be safely applied to the spokes after that repair?
The mag wheel repair., I would trust running it after that workman's repair.
I think it would be interesting to somehow x-ray that formerly bent section to see what you mean..
I've seen bent alloy rims;most of the time a sharp bend like that will occur because someone hits a curb+ they don't check their tire pressure every day/week..
