It worked, but left a little "bulb" near the weld. After careful

such welding, that would make the weld look very similar to
surrounding wire? (TIG)

Silver brazing.

That's what I used to do.

I still get a small blob on the junction.

Too much filler.

Get some .005" flat silver solder from Brownell's, the stuff they use
to stick front sights on shotguns among other things.
Make your ring with about an .005" gap. Cut a piece of silver solder
to fit in the gap. Flux the gap, wipe flux off of metal not in the
gap, stick the little precut bit of silversolder in there, pinch the
ring gently and heat gently until the alloy melts. Capillary action
will keep the molten alloy in the gap.

With TIG, I wouldn't use any filler at all. I'd make the joint with
flat faces and no gap, do an autogenous weld.

Silver brazing is quicker, easier and just as strong.
