Those iron oxide diodes are embedded in a fairly conductive block of
concrete that probably has lower resistance than the diodes, so it's
probably not an issue.
However as far as welding goes, rebar CAN be welded, but it takes a special
technique, and requires some knowledge of the bar material and the right
welding rod. This isn't a "get the old buzz box out and tack everything
together" kind of operation. And, as always with structural kinds of
things, you need to talk to your local regulators. There's been enough
disasters with welded rebar that there is some sensivity to the issue.
