Why would you want to?

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?

It's negligible at the voltage and current that we are talking about here
but the decrease in resistance is from the increased surface area in
contact.
If you were to just lay 2 wires next to each other, the area of contact
would be very small, just the tangential area. Twisting the wires together
will increase the area but soldering will provide the most.
