That looks like nickle welding to me. It weathers to a gray color and will not rust.
It is expensive, best to go to your welding supply and ask. Ni-Rod is what I use. There are several formulations for welding cast iron and each have a high nickle content. Very important to preheat and weld while it's hot, then wrap it so it cools down slowly. Otherwise you're likely to crack next tot he weld.
That part pictured is probably cast steel. But looks like it was welded as cast iron. You can weld cast steel with your favorite carbon steel weld rod. For heavy sections preheat is also advised.
You can tell cast steel from cast iron using a grinder. Cast iron throws red sparks with no secondary bursts. Steel and cast steel the sparks explode away from the grinder. Find a scrap piece of cast iron like a brake drum or engine block and put the grinder to it. It really is a different spark than what you're used to with steel.
If the part pictured is cracked next to the nickle weld you need to repair it with nickle rod as well, even if it's steel.

A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
