[TowerTalk] Cadweld vs other welds or brazing

Given the price of Cadwelds and the high number needed for an extensive 
tower grounding project I am interested in more cost effective 
alternatives. I know some folks braze their copper strips and or wires 
to the copper clad ground rods.  I'm curious if any one here has any 
knowledge of MIG welding copper to copper using copper wire as filler.  
If so, what shielding gas was used and how well did it work?  At first 
glance it seems like a reasonable approach and likely to be much cheaper 
than Cadweld shots.  tT could be an alternative means of making 
connections that can be safely buried with no need for frequent inspection.
