IF soldering is such a bad idea, then why are the windings (which are
made up of solid copper bars) inside an 800 megawatt generator (unit 2

I watched them do this during a repair thirty years ago.

I'd wager silver solder was used.

Tom, you are incorrect. A solder joint under vibration can easily create a
resistive connection and it can be undetectable until it overheats. Please
review my previous advice and use a crimping tool that creats a very high
pressure crimp.

Vibration is not the only consideration, as it is illegal to solder power
connections in a building - at least in the U.S. The bottom line is that solder
is inappropriate for power wires anywhere, other than in a few very specific
applications. Unless you are manufacturing electronic devices, you are unlikely
to encounter those applications.

I agree. The crimp is for a solid mechanical connection. The solder
gives a good electrical connection and resists corrosion.
