I used old 1" water pipe to build a metal fence and would like to attach
some cast iron spear points to the tops. The only one that fits has a solid
base and I need to weld or braze or ? Any one know the best way to do
this?

Thanks,

Explain how it "fits" then we can better serve you.

MIG (wire feed) welding is a lot easier to tack-weld those on, but
stick should work with small rod and a quick hand.

Do some practice tacks with scraps to get down your technique, feeds
and speeds. Then start on the fence and do the back-side first where
nobody will see it, hopefully you'll get enough practice so the
front-side welds look a lot better.

And I hope you already know to use a fan at your back and/or stay
upwind from the fumes when welding anything galvanized like water pipe
- Zinc Fume Fever is nasty, and there are worse floating around with
more exotic metals.

Since no one else has mentioned it, I will. Nickel rod is the best for cast
iron. It works quite well for welding cast iron to steel. If you have both
stick and MIG, then you might try this: put a "butter pass*" of nickel on
the bottom of each spear point, and then MIG it to the pipe. This might
produce a neater, less bulky weld.
