what you have there is a nickle weld you may not have noticed but it does not rust. This type of weld is a stick/arc weld. How it would have be done was a Nickle rod(probably 99 rod AKA cast rod was used) was used to build up a void in the cast before any machining was done. A nickle weld is a good weld for cast and i have used it to repair broken casting. The problem with nickle weld is it can distort machine part if not carefully done. short 1" welds peened with a hammer while cooling is how it is done. I have some in the RM tables
this is my first try at cast welding. I used nickel 99 cast rod so I could work the welds after.
I could use more practice welding ,but I am not to proud to show you. every one starts at the beginning
looking for free tips from the pros?
I did a thread on cast repair thread while back that my be usefull.
