The stainless steel does expand and contract significantly during the heating and cooling of the welding process so its challenging to use. The oxy-fuel gas process is often used for welding cast iron. Pure nickel contains 99 nickel.
Cast iron Welding Rods have a special Graphite rich flux this graphite chemically ties up the Carbon in the Cast Iron limiting migration into the weld metal and heat affected zone.
ArcStick Welding is arguably the best all-round process for Welding Cast Iron provided the correct welding rods are used. Cast Iron Filler Metals for Gas or TIG welding. If the welding rod has a high amount of nickel copper and other material that means this is the one you need to weld cast iron. One is iron and the other is stainless steel.
