OVERVIEW

Premium Nickel Alloy Electrode for Cast Iron Repair

The UTP ECONOCAST 99 is a high-performance stick electrode designed specifically for the welding and repair of cast iron components. Classified under AWS A5.15 as ENi-CI, this electrode features a commercially pure nickel core wire that is essential for producing soft, ductile weld deposits. Industrial maintenance teams and fabrication shops rely on this consumable for critical repairs where post-weld machining is required. The 4.54 kg (10 lb) packaging ensures a substantial supply for extensive repair projects or ongoing maintenance inventory.

One of the primary challenges in welding cast iron is the formation of brittle martensite in the heat-affected zone, which often leads to cracking. The UTP ECONOCAST 99 mitigates this issue by operating effectively at low amperage settings. This reduced heat input preserves the base metal's integrity while ensuring excellent fusion. The electrode is formulated to provide a stable, spatter-free arc that is easily controllable, making it suitable for welders of varying skill levels. It performs exceptionally well in all welding positions, allowing for in-situ repairs of heavy machinery without the need for disassembly.

The resulting weld deposit from the UTP ECONOCAST 99 is fully machinable, a critical requirement for repairing mating surfaces, threaded holes, or precision components like engine blocks and pump housings. The slag system is designed for easy detachment, often lifting off with minimal effort, which speeds up multi-pass welding operations. This product is compatible with gray cast iron, malleable cast iron, and nodular cast iron, and can also be used for joining these materials to steel.

FAQ

The UTP ECONOCAST 99 is classified as AWS ENi-CI, which indicates a high-nickel electrode designed for welding cast iron.

Yes, the deposit is soft and fully machinable, making it ideal for repairs that require drilling, tapping, or milling after welding.

This electrode can be used with both AC (Alternating Current) and DC (Direct Current). For DC, straight polarity (DCEN) or reverse polarity (DCEP) may be used depending on the specific machine and preference, though AC is often recommended to minimize arc blow.

While UTP ECONOCAST 99 is designed for 'cold' welding (without high preheat), a slight preheat (around 300°F) can help remove moisture and reduce thermal shock. For complex or thick parts, specific preheat and slow cooling procedures are recommended.

Yes, the high nickel content makes it suitable for joining cast iron to steel, as well as joining cast iron to itself.

Use short weld beads (1-2 inches), weld at the lowest practical amperage, and peen the weld bead immediately after welding while it is still hot to relieve shrinkage stresses.

It is suitable for welding gray cast iron, malleable cast iron, and nodular (ductile) cast iron.

Low amperage reduces the heat input into the brittle cast iron base metal, minimizing the width of the heat-affected zone (HAZ) and reducing the likelihood of cracking.
