joints will just be under normal bedroom floorboards.

cut the cable, install 2 sockets, each cut end goes to one of them,
and add a linking bit of cable. Otherwise you can use a jbox or
crimps. Soldering's also allowed, but with that you should still use a
jbox to enclose it.


Can anyone point me to a recourse about soldering power cables?
I'm not planning doing any myself, but clearly it must involve
more than twisting the wires together and applying the lead-free
equivalent of 60/40.

No need for lead-free - leaded stuff is easier and lower temp to reduce melting of insulation.
Main think is to use an iron (not blowlamp!) that can pump enough heat into the joint quickly
enough.
