ERNiFe-CI (ERNI55)
Alloy Type: A5.15, CAST IRON Welding Electrodes and Rods
ERNiFe-CI (aka ERNI55) is a filler metal used for TIG and MIG welding of cast iron. It is also used to repair castings. The weld metal of ERNI55 is harder than that of ERNI99. A preheat and interpass temperature of 350 deg F minimum is recommended during welding, without which the weld and heat affected zones may develop cracks.
