I work with 1000-1200C resistance furnaces, and my understanding is that the internal connection between the heating element and the power leads is both crimped and welded. It is probably a niche application, and welding and soldering aren't quite the same, but it does happen.

And this is one reason why I love HN, and why I threw in that caveat, because I knew someone would come up with a scenario where it's done. Thanks.

Like I said, I come from the aerospace world, where as another user here said, we solder as little as possible. Sure, components on PCBs are soldered (and even then, they are often covered with an inert, non conductive coating or RTV to fix them in place), but when it comes to wiring and connections, solder joints are asking for trouble when they get vibrated.
