Description
Weld Star – Monel 400 (NiCu-7) TIG (3.2mm) 5kg
Weld Star – Monel 400 (NiCu-7) TIG is a nickel-copper alloy specifically designed for welding Monel. The welds produced have a good bead appearance and offer excellent corrosion resistance, especially in saline solutions. The weld metal itself is highly resistant to a wide range of corrosive media, making it a preferred choice for various applications. This alloy is also frequently chosen for weld overlay tasks.
Features and Benefits:
- Specialized Welding: Designed specifically for welding Monel, ensuring compatibility and strong welds.
- Corrosion Resistance: Offers excellent corrosion resistance, especially in saline solutions, ensuring longevity of the weld.
- Versatile Resistance: The weld metal is resistant to a wide range of corrosive media, making it suitable for various environments.
- Good Bead Appearance: Ensures visually appealing welds that are also structurally sound.
- Overlay Applications: Can be used for weld overlay tasks, providing a protective layer on other metals.
Common Applications:
- Marine Construction: Especially in offshore environments where corrosion resistance is crucial.
- Heat Exchangers & Pipelines: Suitable for components that come in contact with corrosive media.
- Desalination Plants: For equipment exposed to saline water.
- Chemical & Petrochemical Industries: For equipment and components that handle corrosive chemicals.
- Energy Engineering: In components that require both strength and corrosion resistance.
