Hi gents. I'm a newbie so please be gentle lol.
I need some good pointers on how to carry out a repair to a cast turbo turbine housing. The housing in question was removed from a car and found to be cracked through due to heat stresses placed upon it during its normal operating procedure. The cracks are due to the heats which can reach around 1300degrees F under lean operating conditons. The cracks themselves are a common occurance in this type of unit and instead of constantly binning items I would like to attempt a repair. When at college many moons ago I remember affecting a repair on a cast frame by drilling at the ends of some cracks (to stop the crack spread when welding) then heating the material quite a bit and keeping the heat there whilst carrying out the repair. I have a few questions so if I can be pointed in the right direction I would be very grateful. I suspect the repair not to be possible but as I have the facilities and equipment to hand I thought I would attempt it anyway. A company in Europe can offer the repair for a price and this is why I would like to attempt the work myself (damaged parts are in abundance for the work).
1. Would the repair I wish to make be carried out in the same manner? What procedure should I follow?
2. What specific rods would be required to make the repair?
So thanks for reading and hopefully someone may be in a position to give me some helpful information.
