Is cadwelding is the same as "alominotérmica" (term in spanish)?
I.e. Copper oxide + aluminio powder
3CuO + 2Al = 3Cu + Al2O3 + heat

And what about connecting ground roads togehter.
Someone told me I should not use strand copper but the only thing I can get
is 35mm^2 (AWG2) with 7 strands or 50mm^2(AWG0) with 19 strands.
Is it true that this will oxide rapidly and loss the low resistance?
The book I have now says you must use at least 35mm^2 to connect the roads.
