So the problem seems to be sealing the thin metal ring to the thick metal parts.

It has a nice V shaped crevasse that something could be flowed into, seems like Vacuseal should work on something like that unless it can't survive the baking process.
Perhaps if it was a slow enough leak it could be applied after evacuation and cooling were done?

Whatever is used it has to be impenetrable, flexible to some degree, capable of withstanding heat & so on.

I don't imagine there's any way to weld the thin metal to the thick metal without cracking the glass or destroying the seal there.

I knew a guy who could weld aluminum cans together using a Plasma Welder, there's still a lot of heat involved though.
