Cast iron is notoriously difficult to weld because of it's super high carbon content. Also, it wouldn't hold up to the pinion gear slamming into it every time you start your car.

For equally spaced welds, can you count the teeth and use them as your guide? I am not a mechanical engineer by any stretch, but my gut says 4 good welds of about an inch long should do the trick. I am thinking of the resistance when I turn over the engine with a wrench; it is a fairly low torque that is needed .

Ring gears are made of carbon steel and receive a surface treatment, followed by tooth profile grinding.

This should make welding much easier, and I agree a greater number of shorter welds will be better.
