question for the welders

Just had a cast steel hub for hay rake welded at shop, He left me an email saying it come out good, have to pick up later this week. Was going to use wire welder. Long time welding shop said it could not be done but I have never saw a wire welder there. This one said the harder a pull a magnet has on it the better it will weld.
 
My boss always said give it a tap with a hammer . If it tings I weld as normal . If it's more of a thud then use nickel . I guess it's worked so far .
 
without seeing the piece, 7018 should be fine. dual shield may work, or maybe 680 eutectic if you're sure it's steel, but can't identify it
 
For cast steel I use 7018 or dual shield in the big if it's a big job. Nickel is not necessary. It is very easy to weld with 7018.
 
I worked for one of the very few steel sand casting foundries left in the US. When I worked there back in the mid to late 1980's it was one of 8, EIGHT steel foundries left, bet that number is less now, but that foundry is still in business.

Mild and alloy steel castings can easily be welded, they welded EVERYTHING there it seemed. Pre-heating was used on thicker sections. Depending on alloy they used MIG, stick, 10018, 11018, AR, etc rods. Not sure what wire they mig welded with, but the wire was large.

Lot of things I read about here being called a steel casting is actually DUCTILE IRON. Years ago, 1920's, '30's, '40's it was called Semi-Steel. A lot of the castings the foundry I worked for made, they made because they could easily be welded to other steel parts. Same or similar parts I saw later being made as a closed die steel forging.
