Waste furnace overlay welding

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.

Laser Cladding

Laser cladding technology is a new type of hard-facing technique introduced and developed by our company. This process uses a coaxial cladding nozzle that delivers cladding material onto the workpiece surface via a coaxial powder feed, while simultaneously directing a laser beam onto the substrate to create a molten pool. As both the cladding material and the base material melt, they rapidly solidify, forming a surface cladding layer with extremely low dilution and achieving metallurgical bonding with the substrate. This innovative method significantly enhances the wear resistance, corrosion resistance, heat resistance, oxidation resistance, and electrical properties of the base material's surface, enabling precise surface modification or repair. It not only meets the specific performance requirements for material surfaces but also helps conserve substantial amounts of valuable raw materials.

Fully Automatic Alloy Cold Arc Welding Deposition Technology

Our company has independently developed and designed a new automated alloy cold-arc welding deposition technology. This innovative process utilizes fully automated alloy cold-arc welding, combined with the company’s proprietary nano-amorphous alloy materials, to provide advanced wear-resistant protection for the severely eroded water-cooled walls in CFB boilers. As a result, it effectively extends the service life of boiler water-wall tubes, ensuring stable, safe, and reliable operation of the boiler system.
