But is it safe to weld nuts (heat-treated steel and all)?
No. It's sometimes done, but the carbon equivalent is way too high and the welding is very tricky because the fillet lengths are very short. Tack welds in that sort of steel are prone to crack. There's also distortion to worry about. A client of mine invariably prefers drilling and tapping where stripping strength isn't an issue.
