welding cast iron?

[62fairlane]

I have welded stuff cold with nickel rod.



just small short welds with lots of cooling time between to keep the heat affected zone small. welded up a windowed block and a broken starter ear.

currently I have been welding injector bungs into a head for a port EFI setup (intake part of the head on this motor)

My local Sears Hardware carries cast iron arc rods, 3 for $5 I think they are, 1/8" rods.

Not too bad, to give it a shot.

They also carry aluminum rods, and aluminum flux coated rod for gas welding.

The way i do it is drill a hole at the start and end of the crack

Then bevel the crack with a grinding wheel

Take MG stick rod and break the flux off and clean it with emery cloth

Then i TIG it with the welder on DC

It gives you plenty of control and you are garaunteed the crack is sealed as you watch it melt together!
