There must be a word for the opposite of swaging.

Crimping?

Oddly, the definitions I've seen for swaging all refer to reducing the
diameter, but I've always known swaging to be used to refer to
increasing or decreasing the diameter. If you want to specifiy which,
simply using swaging-up or swaging-down.

Didn't know that. I used swaging as a method for joining refrigeration
pipes, but those are thicker than water pipes (also work on ID, not OD).
It's a very sound method: swage, clean up with steel wool, insert,
Cuproflo(?) with oxy-propane (no flux) and a very strong joint in about half
an inch of pipe.
