"you might want to look into resistance soldering. It runs a current through the metal and the heat is very concentrated to just the point being soldered. . . . Not cheap by soldering standards"
I'm wondering, could you use a soldering gun for this?? They essentially use the same method. There's a transformer inside the handle that turns the 110 v. current into low voltage, high amperage current that runs through the copper tip and heats it.?
So you could connect two cables where the tip connects and attach their other ends to the work. That would run the high amperage current through the joint. The cables would have to be fairly heavy so they wouldn't get hot themselves, but I don't know how heavy. (Perhaps speaker cable would work here. It's heavy gauge supposedly for the best sound quality).
I use a Weller soldering gun (the same one I've used since getting it for Christmas at age 12, so they're pretty durable!)? That's 100 Watts. I don't know the wattage you need for resistance soldering, but if a single soldering gun weren't enough, you could hook up several.

If soldering is an option strengthwise, but the issue is heat, then you might want to look into resistance soldering. It runs a current through the metal and the heat is very concentrated to just the point being soldered. It is popular with model railroaders working with small delicate pieces. Not cheap by soldering standards but cheap compared to welders. If you look around there are also some DIY articles.
