Inconel 690 Welding Rod is a high-performance filler metal designed for welding applications in extreme service environments that involve high temperatures, aggressive chemicals, and oxidizing conditions. Manufactured with a high concentration of nickel and chromium, this rod delivers excellent resistance to corrosion and oxidation, particularly in chloride-rich or acidic settings. Labdhi Metals, a prominent manufacturer, stockist, and exporter, provides Inconel 690 Welding Rods in various diameters and packaging options to cater to industries such as nuclear power, chemical processing, and marine engineering.
The high chromium content (27–31%) of Inconel 690 Welding Rod imparts remarkable resistance to stress corrosion cracking, pitting, and crevice corrosion. This makes it suitable for overlay and joining of Inconel 690 components as well as dissimilar metal welds involving stainless steels and nickel alloys. Labdhi Metals supplies welding rods that comply with global standards and ensures consistent quality with every batch through rigorous testing and inspection.
These welding rods are particularly well-suited for Gas Tungsten Arc Welding (GTAW/TIG), Shielded Metal Arc Welding (SMAW), and other precision welding applications. Thanks to their stable arc characteristics and smooth weld bead formation, Inconel 690 rods reduce the risk of weld defects and ensure metallurgical integrity. Labdhi Metals ensures that every rod is manufactured under strict quality protocols and is suitable for both maintenance and fabrication projects.
In demanding industries like nuclear energy, where safety and performance are paramount, Inconel 690 Welding Rod is trusted for welding critical components such as steam generator tubing, reactor vessels, and heat exchangers. These rods maintain strength and corrosion resistance even after prolonged exposure to high temperatures, ensuring long-term durability and service reliability. Labdhi Metals provides certification, including Mill Test Certificates (MTC) and third-party inspections (TPI), on request.
