Features and Benefits:
ERNi-CI (Nickel Alloy 99) is used for TIG welding of cast iron.
This wire is extensively used to repair gray iron castings.
It can also be used for overlay and build-up applications.
Dilution from the casting influences the mechanical properties of the metal. Due to the high nickel content, the welds are readily machinable.
A preheat and interpass temperature of 177C min is recommended during welding.
