Salvaging a EN24 grade steel casting
Salvaging a EN24 grade steel casting
(OP)
I have recently cast a ring with a desired OD1140mm and iD 620mm,and thickness 50mm. This has now been found to measure 1131on OD with the ID having sufficient stock. The casting has shrunk more than expected,(which will be a separate topic).
I need to salvage the casting by depositing weld metal on the OD before I take up for machining. E7018 is the welding consumable,process is CO2 welding.
This is part of a tool for forming and OD1128mm is critical dimension as against it the component is formed.
Your comments please on such a salvage operation or is it better to recast?
Thanks in anticipation.

Thanks for the encouragement. eventually the run out was not much and I could salvage the casting with minimum welding.

The following violates our no weld in the working area rule.
Just though about some 1030 high pressure (10,000 psig) valve bodies where we would rework the cage area by weld repair. I do believe that we would stress relieve them at 1100F after welding. At the time stress relief was the same as PWHT. We used 7018 electrodes until about a year before we shut the process down when we went Hast C for the repair. The Hast C stopped all the wire drawing that necessitated the repair.

Moldcore is actually has a good Idea :/, except check with a sheet metal forming shop that can set you casting in a expanding mandrel. if you have enough stock in the I.D., solution anneal the material dead soft, then expand/strech it to the required diameter. :\
I bet the I.D. contract as well as the O.D. which would alloy you to expand it.
I use to round up roll formed and welded steel plate this way.
Please Advise

Take care

You may have to invest in a ring rolling machine.
