8988.3655S - Josef C32 Nickel-Iron Cast Iron Welding Rods 3.2mm

Professional Cast Iron Repair Electrode

The Josef C32 Cast Iron Stick Electrode is a specialized maintenance consumable designed to tackle the unique challenges of welding cast iron. Engineered for professional welders and industrial maintenance teams, this 3.2mm electrode provides a reliable solution for repairing cracked or broken cast iron components. Whether working on grey, malleable, or nodular cast iron, the C32 formulation ensures a stable arc and deep fusion, resulting in high-strength joints that stand up to operational stresses.

One of the standout features of the Josef C32 is its machinability. Unlike standard steel electrodes that can leave hard, brittle deposits on cast iron, the C32 produces a weld bead that can be drilled, tapped, or machined after cooling. This is critical for repairs on engine blocks, pump housings, and gearboxes where precise tolerances must be restored. The electrode is also formulated to be tolerant of contaminants, making it effective even on castings that cannot be perfectly cleaned of oil or grease prior to welding.

Packaged in a convenient 1kg tube, these electrodes are easy to store and transport to the job site. The C32 runs smoothly on both AC and DC+ currents, offering flexibility depending on the available power source. Its controlled thermal expansion properties help minimize the risk of heat-affected zone (HAZ) cracking, a common issue in cast iron welding. For best results, preheating the base metal is recommended, though the C32 is also suitable for cold welding techniques involving short beads and peening.
