Manifold Repair

I thank you for the compliment ,I've been
practicing for many years. I got started because
of all the great welders and their nickel rod made
such messes of cast I knwe there had to be a better method .And this shop being a machine shop (repair
machine work) , and also engine machine and rebuild ,
I get in all kinds of jobs .

The rod is available from most welding suppy also need the flux to go with the rod . Harris/
welco ios one supplier , Tucker valve seat co in
odessa tx is another . Weldmold co in mich has the rod and says that theirs is machinable as the first two are machinable only with carbide . All
the rod was machinable untill about 5 years ago,
something has changed in the manufacture and now
it's hard . I still have 10 or 15 lbs of the old
rod, I keep that for building parts that need to
be drilled and tapped .
Back in the 50's I heard about introducing copper
into the weld , but I didn't understand it then
and since pretty much forgot about it. george

The material that I use to repair cast iron is cast iron in the form of a square rod and comes in several sizes. This repair is not brazing , it is oxy/acet welding. Exhaust gases are not hot enough to melt the cast and I have never seen it melt the brazing material . The material in arc weld rods is mostly nickel
and not cast iron . Most any form of arc weld on
cast does not work well , not to say that it doesn't
work just not well . I started out 35 + years ago
with the idea that arc would fix most anything but
eventually I learned that to fix cast properly you
will use oxy/acet and cast iron rod . If done properly and ground it is almost impossible to find the weld as the rod is color match and material match to the work.
