ERNI99 Nickel 99 Cast Iron Welding Rods Blue Demon

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.
