I'm not talking about an EMBEDDED steel plate, but about butt-welding TWO
1/4" plates together, where if you look through the joint before welding,
you can see the concrete underneath. I'm worried that, even with partial pen
welds where theoretically the weld metal won't quite contact the concrete
surface--though it would stop short a mere couple of sixteenths away--the
radiant heat might damage the concrete in some way.

It is a common detail. I have not seen any failures in the field due to the
local high heat on an embedded steel weld plate.
