Would you buy a car with a welded alloy?

I might, but I would at least want a consideration on price to replace the alloy wheel.

I’ve never had a cracked or welded alloy on a Rangerover but did get a crack on a Jag wheel. Every 6 weeks or so I needed to add a bit of air when the sensor started shouting. It didn’t know it was cracked and assumed that it was just a slow puncture which I would get sorted “next week “ then it never got sorted as it never got any worse I just left it as it needed a new set of tyres shortly.
Ended up doing nearly 20K miles like that.
Only spotted the crack when it went for the new tyres, at the time a new alloy was the cost of 3 new Pirellis. I reckoned that as an unrepaired crack hadn’t got worse or failed in over a year then getting it welded wasn’t a problem so I did just that.
I don’t see a problem with having a minor crack repaired but there needs to be some common sense applied.

Scrap it and get another.
As a coded welder a long time ago, That has had a chunk out of the casting, which will weaken it as it will have a hairline fracture in it. Some places don't repair them properly. A wheel would need pre heat and post heat before welding so as not to affect the grain structure. Tony

Just to put this to bed, I wasn't happy with it so got a new, old stock wheel off eBay for a very reasonable price...

Had the tyre swapped over and the ride has improved, there was a flat spot on the rim for several inches where the weld is which indicates the wheel had a good hit to do that damage and maybe wasn't OK to use...

Anyway, all sorted now, I do have to say the new Pirelli Zero's are superb....  Pete

Glad you got sorted with another wheel, at least you won't have any niggling feelings in the back of your mind!

Especially so, given the flat spot you mention

Obviously not repaired properly if it still had a flat spot, good move 👍
