Patrick, if you do a google search for welding copper there is a pile of  
info there.

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.

Whatchathink??
