What is AWS Class ENi-1 Coated Electrodes?

AWS Class ENi-1 coated electrodes are primarily made up of nickel (over 90%), with small amounts of iron and other elements added to boost strength and compatibility with cast iron. The weld metal typically boasts a tensile strength ranging from 55,000 to 65,000 psi (380–450 MPa) while maintaining excellent ductility and machinability. These electrodes create soft, crack-resistant welds with minimal hardening in the heat-affected zone. They are perfect for welding in any position and work well with both AC and DC current, providing stable arc control and easy slag removal, even on dirty or oxidized surfaces.

AWS Class ENi-1 Coated Electrodes Uses

AWS Class ENi-1 coated electrodes are extensively used for welding gray cast iron and for joining cast iron to steel, nickel alloys, or stainless steel. They are frequently employed in the repair of engine blocks, gear housings, pump casings, machine bases, and broken castings across automotive, marine, heavy machinery, and maintenance sectors. ENi-1 electrodes are particularly valuable in applications that demand strong, machinable welds that can withstand cracking under stress. Their capability to weld on dirty or contaminated surfaces also makes them ideal for on-site repairs and the restoration of aged or worn cast iron components.
