[TowerTalk] CDwelding a tower leg

[David Gilbert]

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.
