"The problem is that solder will melt with just a few amps of current passing
through it."

That simply isn't true.

Yes the
NEC permits soldering but unless you are extremely competent at it its
a bad idea. [more nonsense snipped]
That isn't true either. If a soldered joint can be "ripped apart" as you
described, then it wasn't properly mechanically secured -- which means the
joint wasn't any good *before* it was soldered.
Training involved soldering "western union" and "linesman" splices,
which the instructor then attempted to dissassemble with a linesman's
pliers. When dissassembled you could easily see how well the solder
had penetrated and wetted the conductor - right through the joint.

It was common practice - just like welding training involves
fracturing the weld to see how good the weld penetration was.

hi,
As a result of poor soldermanship(?). I was mil-spec. soldering
certified by U.S. DOD in my working days. I never made a solder joint
like that. Simply it couldn't happen!
Even a perfectly soldered western union splice CAN be dissassembled.
Not easily - for sure.. Solid wire, of course.
