Hello All,
First time poster here. I can melt metals together, but I'm fairly certain only some of it can be considered to be welding
My current challenge is to fill some cracks forming in an OEM exhaust manifold from a turbocharged engine.
The manifold is cast in Ni-Resist NiSiCr 35 5 2, also called ASTM D-5S or BS S5S.
The cracks are forming internally in the variable thickness areas where the runners combine. The cracks have not made it through to the exterior yet.
Having googled this to death I'm looking for some help on selecting the right rod to fill the cracks that can cope with the high temperature cycles of a turbo manifold. What are the choices, pro's and cons?
I expect I need to drill both ends of the crack and grind it out, plus preheat.
