Yep. That's what I'm talking about. You're right in thinking that what
you really get is pair of junctions that are 1) metal A to solder, then 2)
Solder to metal B, but in practical terms if the joint is small and the
process that you are measuring is rather monolithic, like a portafilter
full of hot water and coffee, then the solder cancels out and you mimic the
spotwelded connection. Makes it real easy to make loads of junctions
without needing a spotwelder.
