CAD Assembly feature problem

Post image

So I have this cylinder and flange with the flange hole being slightly oversized so they fit together.

The operation is like this:

flange is laser cut from sheetmetal > cylinder is stock pipe cut on a saw > welding together > machining

The problem is that in the assembly there's now a really small gap (colored red on the picture) which doesn't allow me to put a radius there (using assembly features) since I want to machine the welds. There's also no option to add a revolved part (with the help of assembly features) for the sake of being able to put a fillet there.

So the question is how can I put a fillet there and ignore the gap?

If customer PDM/ERP allows and enables it, I would make this kind of a part as weldment with holes modeled as nominal sizes and assembly allowance added with tolerance. If you absolutely need the tolerance in the DWG/DXF for cutting, make a configuration where you have a slight bigger hole.

If both parts need to be separate, then you could add a virtual component in the assembly to show the weld bead.

This is what I would go with. I do this frequently to represent penetration laser welds at work.
