Welding smells a lot less than someone smoking a cigarette, so I doubt people would complain about that.
However, the noise of someone preparing stuff to weld with an angle grinder would definitely be annoying.

Edit: my point is just that it's weird to police car maintenance specifically, rather than general noise ordinances and/or HOA rules (for people who choose to have an HOA).
The same people complaining about car/mechanical work are the ones who have no problem with consistent leaf blowers/lawn mowers/parties/etc.
