[TowerTalk] Rebar Cage Question

[Donald Chester]

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.
