Ideally, there should not be any gap to fill.

Regarding monoblock barrels made in production guns: Welding and refinishing would be counterproductive to efficient production methods, cost/time savings, etc., which are always high on the list of production items.

I would not be surprised if there are monoblock guns being made that are simply interference fit.
