[TowerTalk] Cadwelding to Rohn 45G and 55G

[Kevin Stover]

In a previous life I was a certified R/D and production welder.
Letting something so uncontrolled as cadweld loose on a relatively thin 
steel tube like a Rohn leg is just begging for trouble.

Yes, the tower section is welded but under exacting conditions, in a 
special built jig, by a human who is in control of the temperature and 
placement of the weld. Not so with a cadweld shot which is nothing more 
than a contained yet uncontrolled exothermic reaction. I'd charge  $150 
just to turn my welder on to fix the hole.
