Anyone know the term for laying double traces of solder along copper traces

No, but it's a dumb idea. It's fairly easy to dump solder "accurately"
on a trace (if not covered by soldermask, hopefully that's obvious) -
just heat and feed solder, it will follow the trace, and you can build
it up quite a ways simply from surface tension. If you need more current
capacity on the trace, bend up a chunk of copper wire that actually
conducts well and solder that on. Solder is a lousy conductor, compared
to copper. The copper will hold more solder on there, but most of the
current will be carried by the copper.
