Cast iron welding

[cliffordl]

The manifold on my Frua has cracked - can anyone help with a recommendation to a cast iron welder in the south-east?

Hi,
   
   I would not recommend having your manifold welded. Specialist cast iron welders are very hard to find and even then there are problems with distortion due to the high preheating temperatures required. If anyone offers you a plain arc welded or tig welded repair walk away, unless you want to have more cracks than you started with (don't ask me how I know).
   
   Occasionally an effective repair can be made by gas or tig brazing but this can also be problematic due to the casting having undergone many heat cycles and become semi porous.
   
   Possibly the most effective solution is metal stitching but it does depend on the location of the crack.
   
   Good luck with whatever method you choose.
   
   Regards Luke.

Slinden look like they can offer exactly what you need welding wise.
   Just be aware that  some machining/refacing may well be needed after welding.

Thanks for your replies - Slinden looks like the route to go down if I go for repair rather than replacement.
