There are a few ways to repair an iron fence. You can either use a metal weld or epoxy to fix the broken pieces back together, or you can use a sealant to cover up the cracks and prevent them from spreading. Whichever method you choose, make sure to clean the surface of the metal before applying any repairs, so that they will adhere properly.
