Selectarc TIG CUNI30

This solid rod is specifically designed for Gas Tungsten Arc Welding (GTAW) of various Copper-Nickel alloys, including CuNi70/30, CuNi80/20 and CuNi 90/10. It is a versatile welding material suitable for demanding applications requiring high corrosion resistance, particularly in marine, desalination, and chemical industry environments. The material conforms to AWS A5.7, ISO 24373 and other relevant standards. It offers a controlled chemical composition with specified minimum and maximum percentages for key elements like iron, manganese, nickel, and copper, ensuring consistent welding performance. Preheating is recommended for thicker sections.

This product is ideal for use in GTAW applications, specifically for the welding of Copper-Nickel alloys in industries such as offshore operations (e.g., marine structures), seawater desalination plants, and shipbuilding. It is also applicable within the chemical industry where corrosion resistance is crucial. The rod is designed for both manual and automated welding processes, and requires careful consideration of shielding gas selection and preheating temperatures based on section thickness.
