Butt weld panel gap

Guess it depends on the climate. have seen bonded panels rust right off. No experience with only summer driven cars.
They bond a lot of panels OEM
Glue and weld? Will the heat from welding affect the glue or is there something that will hold up? The glue would seal that seem nicely.

You have to stay away from the glue like 2” if welding near it.
