I cut up a piece of cast iron to fit the missing lug on this pipe:

That's a one inch hole in the other lug.

The pipe to start with:

Some expert welder will weld the lug on. I suppose he will have to
grind bits off the new piece in order to weld right to the middle.
I'll drill a new hole after the welding is finished.
I've not seen cast iron welded before. Anything to worry about?



Bronze welding may be more suitable as much less heat going into the
pipe, you can also build up thickness and shape easily.



Have you thought of recasting the whole thing?
