Flashing is too thin to weld with exothermic welding (cadweld). Recommend
using sliver brazing or go with a thicker material.
The steel inside the ground rod will almost be guaranteed to corrode when
moisture comes between the copper and steel. Galvanic corrosion will
naturally occur.
How wide and thin is the copper strip? We can custom make exothermic welding
molds to weld the strip to the ground rod as long as the strip is of enough
thickness.

Subject: [TowerTalk] Cadwelding Copper Flashing (?)
I have searched and searched throughout the archives of TowerTalk and have
not been able to ascertain the definitive (or even a good idea) method for
cadwelding copper flashing to copper-clad rods. Is this possible? Has
anyone done it? I did see one email that referred to Cadweld's commercial
molds for doing this but am not sure which product the author was referring
to.
About to put down a ground system for my tower using copper flashing and
would like to hear the best method for making the bond from the flashing to
the rods.
Thanks in advance,
Jason
