Hi,
I am remodeling a bathroom in the basement and after removing the
toilet, found the flange was very corroded and old. I tried scraping
what I believed was a wax ring away to see where the flange began and
pieces of the flange itself came apart (metal).
The pipe has an interior diameter of about 3.5 inches. It's hard to
tell what type of metal it is but I know another shower drain project
(right next to it) revealed copper drain pipes.

My question is, how difficult is it to replace this flange? Does the
flange have to be sealed to the original pipe via some type of welding
or can I simply use a plastic flange, fit it inside the original and
screw it into the concrete with anchor bolts?

Thanks

It appears that you have a 4" drain pipe. You can go to your local home improvement center or plumbing supply and get a Twist-N-Set closet flange. These have a rubber seal on the bottom that seals it to the inside of the existing pipe. It will have to be anchored to the concrete.
I have included a link to show a picture of what you will be looking for.Good Luck with your project and reply back if you have further questions.
