Copper / copper welding generally means brazing or soldering. Both are often prohibited due to the heat burst at the joint during a lightning hit. That surprised me a bit the first time I ran into it, but made sense once I dug out the explanation.

I was going to say the same.  But a true "exothermic weld" is
generally allowed.   But I personally would not trust it because it
like I would a clamp.  You are right in that soldering and brazing is
never allowed.
