Go ahead and weld it. You know more about stick welding than me. If you say nickel will work on cast iron, I'd believe it. I just ordered a cheap flux core wire welder yesterday. I'll get a real mig after a while, but I may get a stick welder soon because they're cheap. I'd like to know how your stick welding goes, if you choose to try it.

Doing that would bug the **** out of me, good luck.

The most common approach to your problem (and the easy way) that I have seen is a hi-tech epoxy with metal in the formula. As for welding, I would recommend TIG welding. It is the most accurate and strong welding process out there. It localizes the heat ( less chance for distortion) and is very controlable to the expert. I would look into having a pro do it if that is the route you want to take.

Good Luck.

A good weld should be stronger than the actual material you are welding.. so I dont see why it wouldnt hold. Just make sure someone who knows what they are doing does it.

its not the weld hodling up u shoudl be worried about its if it will stick to teh cast housings, its a little harder to weld to some types of cast tehn others

weld it then tap it with a welding hammer and check if its stuck good and doesnt pop off, i say do it and see what happens i woudl if it was MY car, no wif u are buildign a car fo ra customer thats a diffrent story...
