[TowerTalk] Cadweld vs other welds or brazing

[Patrick Greenlee]

Mechanical fasteners may or may not remain tight through heat cycling, 
freeze/thaw cycles, and possible corrosion which is why they need to be 
inspected and potentially touched up periodically. This is a PITA if the 
connections are buried as per authoritative guidance.  This burial thing 
is one of the motivators for wanting to weld the connections.

Can't respond to the material alteration issue as I don't understand 
what is meant.
