Production Description
The AWS ENi-CI (Z308) Cast Iron Welding Rods are professional-grade welding consumables engineered for the precise repair and joining of cast iron components. Featuring a pure nickel core combined with a strong graphite-reducing coating, these electrodes ensure superior metallurgical compatibility, making them the ideal choice for industrial maintenance and precision tool manufacturing.
Designed for versatility and efficiency, the ENi-CI welding rods are compatible with both AC and DC power sources. Their advanced formulation eliminates the need for preheating the weldment, significantly reducing preparation time while providing exceptional resistance to cracking and excellent post-weld processability for machined parts.

Frequently Asked Questions
No, one of the primary advantages of the ENi-CI (Z308) electrode is that preheating the weldment is not necessary, allowing for efficient cold welding.
For optimal performance, electrodes should be baked for 1 hour at a temperature of 150±10℃ prior to application.
You can eliminate welding stress and avoid cracks by carefully hammering the welding seam and utilizing small current welding to reduce impurity penetration.
The ENi-CI welding rods are designed for use in PA (flat) and PB (horizontal-vertical) welding positions.
Flame straightening should typically be performed between 700℃ and 850℃ (fuchsia) and must not exceed 900℃ (bright red) for low alloy structural steel.
Watering and rapid cooling are strictly prohibited because they can induce brittle cracks and adversely affect the mechanical properties of the steel.
