Since solder is such a poor conductor, why use it?

Why would we not weld all joints. Welded silver or copper wire would not have the loss of conductivity of going through solder.

Tbg I spent 20 years as an electronic tech in the USAF and there was nothing special about the solder we used. Yes I was soldering components on boards as well as connectors used in aircraft. Now maybe NASA uses something special, but I doubt it. A good solder joint is going to last. It just has to be done properly. That's what quality control is for.
