ERNi-Cl (Nickel Alloy 99) is used for TIG
and MIG 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 350ºF
min is recommended during welding.
