It's intriguing to me that those hardware store compression clamps that use 
a hex head bolt pressing against the inside of a ring-shaped bronze casting 
are code-approved for ground wire to ground rod connections.  You'd think 
that such connections would be very prone to corrosion and breakdown.  I've 
even got some of those here that state on the package that they are OK for 
buried ground connections.

The contrast between that and a cad-welded connection could scarcely be 
greater.  Maybe one of the practicing or retired electricians who frequents 
this list could elaborate on why the compression method is considered OK.
