Just got some cheap alloy track rims secondhand, thought this was a crack at first but upon inspection it seems like the weld seam - would it be unsafe to ride this?

weld seam

They're not welded, they're either pinned or sleeved. There's a couple of hundred Newtons of hoop compression pushing the two ends together, so nothing to worry about.

Thanks as ever for answering all the inane queries. Building a bike has thrown up so many questions which I usually have a rough answer to but you never really want to fuck with 'maybe' when getting it wrong means possible dental implants and half a year of recovery..
