If you had done the math first, you would have noticed that 1. Yes, the resistance at the joint is higher than the resistance of the wire and 2. its is negligible. Wires are NEVER oberated at their physical limit. They are operated at currents where "gets warm but you won't burn your fingers" is the basic idea. You may go ahead and invent a connection where the copper really connects on its full crossection, but I predict you are going to end up with mechanically complicated connections that save a few milliohms.

The way this was done there may be a cavity between the strands?
