When we need higher mechanical strength from a solder, we use 2% silver
solder. It's a lot stronger and not terribly more expensive. Melting
temperature is about the same.

I think the trick is to use a heavy enough hammer -

I have to give Jay big yay for the perfect answer. Solder loses any ability
to create a useful joint when it liquifies, hence the need for some very
solid mechanical joining means. The failure modes are truly bad with power
involved.
Agreed; a good answer.
Solder is
It looks similar to Electrathon. The organization says they have 500 schools in
Europe participating. It looks like it is newer in the U.S.A. From a quick scan
of the rules, it looks like an existing Electrathon vehicle might be able to
compete if it has four wheels, uses GreenPower's batteries
