Cast Iron is not created equal. What you had was good stuff. There are some, that if you did what you did, would crack while you were sippin' on your margarita watchin' it cool.
Preheat is important. You did that. Low....but you had some.
Stress relief is important. You did that. Peening of any kind is good.
Multi pass works better than single pass. You did that too.
Stainless will work, with most good castings, and you used it.
Although....stainless with some nickel in it would have been better....but you used hat ya got.
Most rods & wires for cast iron, are 50% nickel or better.
Most that are for welding steels to cast iron, are less nickel.....25% to 45%.
You vee'd out both sides. Good practice.
(FYI You can also vee out one side, run a stringer, and then vee out the opposite side....to keep things all in line.)
No harm in grinding & re-welding. Keeps things warm....and will somewhat blend the parent material with the filler.
Not turning on the gas......no cocktails for you!
Today's solutions are tomorrow's problems.
