Don,
I built my cage from "weld quality rebar" and it was welded by a friend.
My friend is a certified master welder at a nuclear power plant here in
Virginia. It took him the better part of a day to do all the work for me.
Believe me, he knew what he was doing and it still took him that long.
Fortunately he did it as a friend, free of charge! It weighed over 400#
when done. This cage was built to spec for a USTower 72' stand alone series
of towers. I wanted to employ a Ufer ground and that calls for a welded
cage. As mentioned in another post, it requires a special type of rebar
(quality of metal mix is monitored) and it's only a little more expensive
should you decide to go that way.
Drop me a note if you would like some photos and keep us posted
regarding your progress.

I have heard it said many times that one should not weld the rebar cage
together, but tie it together using tie wires. But I have never heard any
explanation of why.
What problems would be caused by welding? I can't see how such a minor
detail would make any significant difference, but a welded cage is certainly
easier to handle before the concrete is poured in, and less likely to fall
apart just as the concrete is being dumped.
