Can Cast Iron and Steel be welded together?

We can weld.... but its critical to weld a cast iron since they usually cracked during welding.... but nothing is impossible it is possible if we stick with the conditions usually the welding rod used is AWS5.15

ITS WELD ABLE BUT SOME CRACK IS APPEAR

YES, bY PROVIDING PREHEATING

Cast iron is difficult, but not impossible, to weld. In most cases, welding on cast iron involves repairs to castings, not joining casting to other members. ... Cast iron typically has a carbon content of 2% - 4%, roughly 10 times as much as most steels. The high carbon content causes the carbon to form flakes of graphite.

Yes it can be weld.

However cast iron has high carbon content and cracking risk is more high. so special prcautions and procedures to be follow.

yes we can weld cast iron to steel using pure Nickel electrode.

Yes with MIG welding using 308 Wire
