Default Looking for Inconel 82 filler rods

My headers #2 & 3 are cracked at the flanges - pretty standard failure after 25+ years of use. I know that I have to use Inconel 82 to TIG weld these from outside. The problem is that this material is super difficult to get here. I contacted one of the largest welding material suppliers in PL and they advised that Inconel 82 is not available but they can sell me an equivalent - pretty much the same metal composition made by Lincoln. The problem is that I have to buy 5 kg instead of 5 rods and the price is insane $500!
Does anybody have excess of Inconel 82 TIG rods and wants to send few in bubbled envelope or small package? Just asking...

Maybe these guys can help you out. They were resourceful when I was exploring an all Iconel exhaust setup.

I asked my brother in law who is a welder and e said incknel should be pretty common for oil and gas especially in subset applications. I asked him about welding a t3 flange on the pipe and he said for a non structural part it should weld quite similarly to stainless. Sorry I can't help with the rod.

From what I was told by two different aviation exhaust repair shops, the filler material won't matter much. Neither was interested in attempting a repair, due to the age/life of the header material. Apparently the metallurgy of the worn out inconel isn't likely to result in a successful repair.

But people reported successful repairs? I believe a lot of listers repaired their headers and call it a success.

I repaired them with standard nickel filler then wrapped them with titanium-fiberglass header wrap. About 5 years and counting, including multiple tracks days.

I purchased Thermanit 625 filler rod - apparently it has 65% Nickel content and is a good substitute for Inconel 82.

purge to inside with argon when you do this, the weld will be as nice on the inside as on the outside, No Burning or stalactites...

You can just tap a regular nickel welding rod lightly with a small hammer to get the flux off and use as a tig filler.

Not sure nickel holds up to heat that the manifold could see though.

I got it welded by a qualified welder, it looks nice although I don't have a photo to show it here.
