CI 115 Nickel Electrode – Crack-Free Welding for Cast Iron & Steel Joints

📝 Introduction:

Welding cast iron has always been a challenge due to its brittleness, high carbon content, and sensitivity to heat. That’s where the CI 115 Nickel Electrode from MAXIDURA brings unmatched performance. Designed for precision repairs and fabrication, CI 115 is ideal for cold and hot welding of grey, malleable, and nodular cast iron components. With smooth arc stability and superior crack resistance, it’s a must-have solution for industries relying on strong CI-to-MS (cast iron to mild steel) joints.

🔍 Why CI 115 for Cast Iron Welding?

Cast iron is notoriously difficult to weld due to the possibility of cracking during cooling. Standard electrodes often fail in critical repairs — especially on oil-soaked, aged, or worn components. The MAXIDURA CI 115 Nickel Electrode was formulated to address these issues. Thanks to its nickel-rich core and machinable weld deposit, it allows both structural integrity and post-weld finishing.

It is designed for:

• Cold welding, where preheat is avoided

• Hot welding, for thick sections

• High-responsibility CI-to-MS joints

• Applications involving vibration, thermal cycles, or pressure

⚙️ Key Features of CI 115 Nickel Electrode

1. Nickel-based Core: Provides high ductility, flexibility, and excellent crack resistance.

2. Machinable Weld Deposit: Allows easy post-weld grinding or shaping.

3. Smooth Arc Stability: Ensures uniform bead profile and minimal spatter.

4. Dual Compatibility: Operates well on AC and DC(+) current, adaptable for various machines.

5. CI-to-MS Joining Capability: Bonds cast iron with mild steel cleanly and strongly.

6. Cold & Hot Weld Options: Suitable for both techniques depending on base metal thickness.

🏗️ Applications

The CI 115 Nickel Electrode is widely used in:

• Foundry castings

• Engine blocks and machine beds

• Pump housings and gearboxes

• Bearing caps and press frames

• Agricultural and mining equipment

• CI-to-steel fabrication in structural frames

Whether you’re restoring a cracked machine bed or fabricating new components, this electrode delivers reliability every time.

🔧 Working Parameters

• Welding Current: AC / DC(+)

• Preferred Technique: Short arc, cold weld for thin sections

• Preheating: Optional depending on casting thickness

• Post-Weld Heat Treatment: Generally avoided to maintain integrity

• Slag Removal: Easy, self-lifting slag for better finish

• Position: All-position welding possible
