If either of you do price them, I'd be curious. Especially if they end up
being good at forming seals leak tight enough for cryo fluid plumbing in
thermal vacuum chambers...
I didn't realize how much harder it is to get LN2 plumbing leak tight
enough to hold a 1E-6 Torr vacuum than it was to make it bubble tight
enough for rocket test stand applications!

They say “less costly” which is usually code for “very expensive”. Have
you priced them?

I strongly suggest Cryofit couplings. I have not used them specifically,
but I have developed a similar technology. I think Cryofit can just sell
you the fittings for whatever tube you want.

JPL says they can do it. I'd be hesitant to base a design on something
only JPL has the capability of, but there's proof of concept.
I haven't seen a lot of autogenous welding in aluminum, and orbital
tube welders are usually autogenous welders. Can make inserts but it
makes the whole thing a bit more of a hassle.

Does anyone have any experience with orbital welding of small (1/4",
for aluminum?
I've seen it done for stainless, but I'm wondering if it can be done
