Strongest metal adhesive
Discussion
Araldite make a specific Araldie for glueing metal called "Araldite Rapid Steel". I have used it and am happy to recommend it.

I used to make specialist adhesives. If you can get hold of some Permabond Flexon, that's about as good as it gets. They used it to hold together bits of Thrust SSC so it's pretty good 
. That is as long as they still make it. I have no idea if they do anymore it was a long long time ago

This, Araldite is potent stuff! http://www.amazon.co.uk/ARALDITE-RAPID-STEEL-ADHES...
Epoxy? I'm not so sure as most epoxies are brittle. Polyurethane adhesives might be a better bet or a cyanacrolate adhesive (now available in a tremendous number of flavours)
At the present time I've been researching adhesives with a view to repairing an obsolete LVM Aerogen 3 wind-turbine-generator designed for sailing boats. When I bought it the machine turned OK and when the output wires were shorted it became stiff to turn so it was working OK. I stored the machine for a few years but when I came to play with it it wouldn't turn!
Stripping the machine revealed the fault. The stator is perfectly conventional like the stator in a car alternator. The rotor however is made from steel and it has permanent magnets (ceramic magnets) glued to its periphery. It appears that the glue has caused a chemical reaction that rusted the steel hence the bond strength was lost. As the magnets are not fussed as to whether they stick to the rotor or the stator there was a problem. Ideally the magnets need to be drilled and fastened to the rotor with non-magnetic countersunk screws but this is easier said than done! Apart from the glue the machine is built to virtually Milspec quality so it is well worth repairing. The problem is getting the perfect type of adhesive.
Allegedly some of the latest cars are made from very thin steel which is glued together! The problem of course is repairing the car after a crash as the original OEM glue strength cannot be achieved in the aftermarket. There are however repair systems available as it would be quite absurd to have to re-shell a car after it had had a little "ding". Look for "Crash Resistant Adhesive". Here is one that I found earlier. Good luck!
