Manual Metal Arc Electrodes are essential tools in modern welding, offering versatility and reliability for joining a wide range of metals. The Ni202 electrode is a prime example of such a product, specifically designed for welding nickel-copper alloys. It conforms to both GB/T EN4060 and AWS A5.11 ENiCu-7 standards, ensuring consistent performance and international quality assurance. This electrode is characterized by its core wire composition of Ni70Cu30, which aligns with the Monel alloy family, providing excellent corrosion resistance and strength.
The Ni202 electrode features a titanium-calcium coating, which contributes to its stable arc operation and smooth metal transfer. The deposition metal contains carefully balanced amounts of manganese and niobium, enhancing its resistance to cracking during and after welding. This makes it particularly suitable for applications where thermal stress and solidification cracking are concerns. The chemical composition ensures robust mechanical properties and durability in the welded joint.
In terms of operational performance, this Manual Metal Arc Electrode excels with its user-friendly characteristics. It operates effectively on both alternating current (AC) and direct current (DC) power sources, providing flexibility in various industrial settings. The arc ignition is smooth, and the welding process is characterized by minimal spatter and easy slag removal. These attributes contribute to high-quality weld beads with an aesthetically pleasing appearance, reducing the need for extensive post-weld finishing.
The primary applications of the Ni202 electrode include the welding of nickel-copper alloys and dissimilar steels, where it ensures strong, crack-resistant joints. It is also employed as a cladding or overlay material to provide corrosion-resistant surfaces on base metals exposed to aggressive environments. Typical industries benefiting from this product include chemical processing, marine engineering, and oil and gas, where reliability under demanding conditions is critical.
The Ni202 represents a high-quality option within the category of Manual Metal Arc Electrodes, combining excellent welding performance with robust metallurgical properties. Its compliance with international standards and adaptability to both AC and DC welding make it a dependable choice for professionals seeking reliability and efficiency in nickel-alloy welding operations.
