can't speak for what they did, but diffusion pumps (hi-vac)
coolant water tubing are often silver soldered onto the pump
in a hydrogen furnace -- it's a sealed "kiln" that has pure
H2 bled through it into a stack above the building where it's
burned -- obviously dangerous so must be carefully monitored
and controlled -- but it produces oxide free joints.  They
wrap the tubing around the pump housing with silver solder paste
(still talking "real" silver solder, not "silver-bearing" tin-lead
alloy) put it in the furnace and .... voila'  purrfect joint.
