Gasification furnace surfacing
HCMT cold welding technology is an anti-corrosion process we developed at our company—based on an internationally advanced welding system platform—after extensive independent research, development, and process design. This innovative technique is specifically tailored to combat high-chlorine and alkali corrosion in applications such as waste-to-energy furnaces and biomass boilers. The key advantages of our HCMT cold welding process include low heat input, enabling single-pass deposition that achieves both the required thickness and iron content for the protective layer. Reduced heat output translates into lower dilution rates and minimal thermal distortion, significantly cutting down on post-weld correction efforts. Importantly, this approach minimizes thermal damage to the base material—a critical factor for membrane-type water-cooled walls, which often endure substantial operational stress. Leveraging the exceptional performance of the HCMT cold welding system, combined with the outstanding corrosion-resistant properties of nickel-based materials like Inconel 625 under high-temperature conditions, we’ve created a comprehensive solution designed to protect the heating surfaces of waste-to-energy furnaces and biomass boilers. This cutting-edge approach effectively addresses the persistent corrosion challenges faced by these critical components. Compared to conventional water-cooled walls without any weld overlay protection, equipment utilizing our HCMT cold welding technology demonstrates significantly extended service life under identical corrosive operating conditions.
