welding cast to stainless

[Cippee]

If you weld cast iron in small runs and let it cool in between runs you can weld it without preheat. Some pieces are too big for me to preheat evenly. Also I tend to be on the lazy side at times. Sorry jerky I didn't mean to sound rude or snotty about the 400 series. I didn't realize how my post sounded until I read it.

its ok, i was just trying to get across that some 400's do have nickle, but most dont. as for cast, you also need to "peen" the weld, witch is hitting it with a hammer to allow the deposited weldment to "stretch" so it wont crack when cooling.
