Jeff:

    I agree with George - R25/45/55/65 is probably too thin to Cadweld to 
directly.  Such high temps could weaken the metal at the place of welding and 
down she comes.

    When I worked as an engineer at my local electric utility company, our 
construction crews would Cadweld ground cables (2/0 or larger galvanized steel 
wires) to substation structural steel.  However, these members were inch thick 
slabs of solid steel so the heat of Cadwelding didn't harm them.  I believe 
(but don't have numbers to back this up) that solid steel towers ought to be 
capable of taking a direct Cadweld joint. 

BOTTOM LINE: DON'T DO IT.

It's a good idea if the leg wall is thick enough (and I don't know the
definition of thick enough)- I've seen it often on commercial towers.
BUT, I'm pretty sure Rohn 25/45 is way too thin for this.
