Alloy 55 Welding Electrode (ENiFe-CI)
Specification
AWS Class ENiFe-Cl is a welding electrode with the AWS A5.15 classifications. The electrode comprises nickel, iron, and copper, and it’s also commonly known as ENiFe-Cl. It’s a consumable electrode used in welding to join non-ferrous metals, particularly copper-nickel alloys. This article explores the composition, physical and mechanical properties, heat treatment, corrosion resistance properties, and uses of AWS Class ENiFe-Cl.
ENiFe-CI Nickel 55 welding electrode is designed for welding grey iron castings to themselves as well as joining them to mild steel. It can also be used to repair castings. The welds are moderately hard and require carbide-tipped tools for post-weld machining. A preheat and interpass temperature of not less than 350⁰F is recommended during welding.
