Better contact and less electrical resistance.

Can you explain how solder between two copper wires provides a lower
resistance connection than direct contact between the wires?

More surface contact? Electrons tend to flow on the surface of a wire
more so than in the center for some reason or another.

I always thought the reason for not soldering was after-the-fact heat.
Depending on the lead/tin ratio of the solder, it can have different
melting points. If a soldered wire heats due to a heavy load, it may
be hot enough to break the solder joint if the solder used had a low
melting point. Just what I was taught.
