One consideration that I can think of is that the tower legs are similar
metals ... both steel and both galvanized. I was always under the
impression that one major advantage of cadwelding was that it provided a
superior and reliable metallurgical bond between the copper wire and the
tower leg.

Question:
None of the tower sections are Cadwelded. They are bolted together.
How is it that these bolts make an adequate lightning connection but
one "has" to Cadweld the ground wire to the tower at the base?
Clearly the sections have to carry as much current as the ground wire(s).
Maybe a dumb question but some explanation more in depth than "it's
code" is sought.
