Description
Welding cast iron requires precision and the right type of electrode. The JAVWELD Nickel Cast Iron Electrodes Ni55 – 2.5mm x 1KG are specifically designed for cold welding applications where minimal heat input is critical. These electrodes contain approximately 55% nickel, offering excellent strength, machinability, and ductility—making them ideal for high-quality cast iron repairs.
The Javweld Ni55 electrodes perform well on gray, malleable, and ductile cast iron. They are perfect for repairing engine blocks, gearbox housings, cylinder heads, and machine bases. Thanks to their low heat input and smooth arc control, these electrodes help reduce the risk of cracking and distortion during welding.
With a smaller 2.5mm diameter, these rods offer better control for fine repairs and allow precise work on thinner or more delicate castings. They can be used with both AC and DC welding machines, providing flexibility on-site or in the workshop. This 1KG pack is convenient for light repairs, maintenance tasks, and touch-ups.
These electrodes create a soft arc with minimal spatter and easy slag removal, resulting in clean, professional welds. They’re also machinable, allowing you to shape and finish the welded area after the job is done.
To ensure the best results, always clean the area before welding and keep interpass temperatures low. Short beads and peening between passes can help manage heat buildup and prevent cracking.
Whether you’re working in the automotive, agricultural, or manufacturing sector, JAVWELD Ni55 2.5mm electrodes are a dependable solution for welding cast iron.
