I do know Cast Iron manifold advantage is on its strength. But i would like to know this. Is it very tough or difficult to unweld flange from cast iron manifold?

you cant weld on cast iron. if ur trying to add on a tap for a sensor, ur gonna have to bore a hold and thread it, then add a tap that way. but anyways, no, you cannot unweld anything on a cast iron.

Yes you can weld cast iron... Just use a nickel rod Preferably preheat the cast iron manifold up to temperature, weld it, and then wrap a heat blanket on top to slowly cool it off.

Lots of factory OEM parts, such as engine brackets, manifold supports, etc.. are sometimes two cast iron pieces welded together.
