I'm trying to source a steel disk of 50mm or slightly greater where I
can weld a nut in the centre and retains an element of rigidity.

I'm currently using:

really its too large a diameter though not a serious issue but is too
thin where it distorts badly whilst welding a nut in the centre.

Are there any off-the-shelf sources I can obtain a couple of these that
are 2-3mm thick? I've run out of ideas!

You can buy steel on Ebay. Maybe even a washer etc in the dimensions you
need - although I'd be inclined to just get some steel - perhaps an offcut
from a local fabricator - and cut to size. Easier to get it true after
welding.
