That's welding to cast steel, do a search on welding cast steel /cast iron heat brings the slag, impurities to the surface making a weak weld. You can pre heat the casting to help the weld take but without the correct heat treat after the piece is both unpredictable in strength and the welds are never going to be the best even using nickel rods or wire. At work we won't even entertain welding cast steel all we will do is braze the 2 pieces but not for strength work.
