It won’t matter much that we have a terrific welder in Calgary Alberta who welds cast (and everything else) welded my cast exhaust manifold when the g d muffler shop hung the exhaust off the manifolds while they were wrestling them into alignment and fastening them down. Can’t account for stupidity. But it’s Trillium Industries in Calgary if you wanna ship it up and have them do it. It was the outside ‘ear’ on the leading port and they got it.M.
Also agree. They only time I've heard of successful
cast iron welding is when it involved a cracked block. With a block, there's
plenty of 'meat' to work with, so you can cut a V-channel into it before
beginning the welding process. For an exhaust manifold, you're done
for.

I'll
second that. You will be well advised to spend time seeking a replacement than a
welder. The fellow who proposed JB Weld, an epoxy, a plastic, must have been
kidding. I hope so. Dan
In my opinion, the task is nearly impossible. There
has been discussion on this topic in the past and I don’t recollect anyone
having more than short term success with a manifold. The process requires the
manifold to be heated to an almost molten state before a weld can be
successful.

Well I received a call from the welding shop I took my broken
manifold to today. They were able to weld it together but upon striking it
with a hammer to make sure it held, it cracked again. Then the welder
suggested I use JB weld to fix it. I don't know if it cracked along the weld
or elsewhere as I haven't seen it yet but I plan on picking it up tomorrow and
taking my business elsewhere.
Does anyone in the Midwest or Southeast Wisconsin area have any
recommendations of a welding place that can handle a cast iron
manifold?
Thank you in advance.
