I'd like to share my experience regarding the welding of steel castings.
A few months ago I had a pair of knuckles with wear from the brake pads.
Took them to a guy to fill the wear by heliarcing them.
The weld turned very hard which is fine by me because it will prevent furhter wear.
Later on I had to have some other steel cast parts welded. Again the weld turned real hard even though the filler rod was mild steel. I was told that the base metal influences the welded area, metal from both gets mixed up creating a hard weld.
The base metal is soft, the filler is soft, the weld turns real hard.
Asked around a bit and it seems that there is no way to have a steel casting welded with the welded area to be like the original.
At least that's what I was told.
