Dude, I've talked to several seasoned, professional welders, and none of them would go near cast iron, it has a different chemical composition than steel.
Also, It doesn't matter if it's structural or not, if the weld cracks you're leaking exhaust all over the place.
I was just trying to find out what process is being used for this so that I can decide whether or not to give it a try.
