Given the attempts to find a way to get copper strip to work well as a DIY-able battery connect it got me wondering the question:
What would happen if you place a wee blob of solder paste between cell and copper and then zapped with the spot welder?
An initial google throws up someone who tried for other reasons with Nickel and had promising results: https://electricbike.com/forum/forum/main-forum/diy-discussion/37105-homemade-spot-welder-issues-turned-into-soldering-device
If this were viable then it could potentially offer a strong set of advantages - short amount of heat on the cell but with wide contact area, but most of all it would potentially allow welding of much thicker copper strip as the melting point of solder is so far below the melting point needed for a spot weld, even with the thermal conductivity of copper it would seem to me that there would be enough heat generation to flash melt the solder.
Thoughts?
