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.

     Umm, good advice for big commercial type towers but  Cadwelding to a
Rohn 25G, 45G or 55G leg will blow a hole in it.
