I used to repair a lot of these for ranchers
when I was working at the trade and they held
up good. I'd bevel the joint, preheat the whole
needle with a rosebud and weld with high
nickel rod (we called it 'ny-rod') on AC or DC.
I'd grind back to smooth, peen it a bit and let
her go; the boys broke new needles about as
often as they did the repaired ones. Here's a
tip for cast iron: keep the heat uniform
throughout the workpiece; that doesn't mean
that you have to have all of it at welding temp.
just elevated to 2-300 degrees -guessing at
that but it will fry spittle :-) For instance when
you're welding up cracks in a cylinder head
you put it under a Cal-Rod hood and bring it
up good and hot, weld a bit then drop the hood
on it for awhile - come back later and do some
more, and so on. After you're thru welding you
bring it back to even temp under the hood then
pull it out and bury it in a box of sand to cool for
24 - 48 hours. When I went to trade school my
welding instructor had welded in the
shipyards during the 2nd World War (18 hours
on, 6 off, 18 on......) and he would weld up
small cast pieces and drop them in the
quench tank!!??.....kept it uniform, right? He
was a wizard when it came to the weldors'
craft and most of his knowledge was OJT
(OnJobTraining) so get in there and go for it
and "if at first you don't succeed.......do it again
only different" ....you'll get it. :-)
