Industry-leading solutions for surface modification and repair
In the era of Industry 4.0, the demand for high-performance surface engineering has skyrocketed. Laser cladding, once a niche laboratory technique, has emerged as the cornerstone of sustainable manufacturing and high-value component repair. As a leading China Laser Cladding Supplier, Shanghai Duomu has observed a paradigm shift from traditional thermal spraying and hard-chrome plating toward laser-based additive manufacturing.
Laser cladding (also known as Laser Metal Deposition) utilizes a high-intensity laser beam to melt a substrate surface while simultaneously introducing metallic powder or wire. The result is a metallurgical bond with minimal dilution, a tiny heat-affected zone (HAZ), and exceptional mechanical properties. This process provides an unparalleled "Information Gain" for engineers seeking to extend the lifespan of critical assets in corrosive and abrasive environments.
How Shanghai Duomu leverages the world's most robust industrial ecosystem
China's "Greater Bay Area" and East China industrial clusters provide immediate access to high-purity alloy powders, high-power fiber lasers, and precision CNC components. This proximity allows us to move from custom design to factory floor 40% faster than Western counterparts.
Our facilities utilize high-speed laser cladding systems that can achieve deposition rates exceeding 5kg/hour. For global enterprises, this means we can handle bulk orders for hydraulic rods or coal mining picks without compromising on lead times.
We incorporate real-time monitoring of the melt pool and closed-loop feedback systems. Every cladding layer is documented, ensuring 100% traceability and adherence to international ISO and ASTM standards.
From deep-sea drilling to aerospace exploration
In Oil & Gas, the real cost is downtime. Laser cladding of mud pump valve seats and drill stabilizers provides a surface that withstands high-pressure sand erosion far beyond standard hardened steel.
Repairing turbine blade tips and engine casings requires extreme precision. Our robotic laser cladding systems allow for localized repair, saving millions in replacement costs while maintaining flight-certified structural integrity.
Continuous casting rollers operate in high-temperature, corrosive environments. Applying a Stellite or Nickel-based alloy layer via laser cladding doubles the service life between maintenance cycles.
Shanghai Duomu's Technical Department specializes in the optimization of the Plasma Transferred Arc (PTA) and Laser Cladding intersection. Our independent R&D team focuses on solving the common "Dilution" problem. In PTA hardfacing, achieving a high-quality overlay is not only about selecting the right alloy powder but optimizing the heat input to ensure maximum hardness with minimum base metal contamination.
Our DYY-LC501 and DML series equipment are designed for efficient long-term operation, supporting large-scale remanufacturing projects. We provide complete industrial equipment solutions, from small-scale manual torches to fully automated gantry-style robotic systems.
Where the industry is headed in the next decade
Traditional cladding reaches 2m/min; next-gen EHLA reaches up to 200m/min. This makes it a viable, eco-friendly replacement for hard chrome plating on large shafts.
Graded materials, where the alloy composition changes through the thickness of the cladding, allow for a soft, tough interface transitioning to a hard, wear-resistant surface.
The demand for portable laser cladding units is growing, allowing for the repair of massive equipment (like hydroelectric turbines) on-site without disassembly.

"Improving PTA hardfacing efficiency is not simply about increasing welding speed. In industrial production, the real efficiency depends on the stability and duty cycle of the machine..."
"For screw conveyors in mining and cement industries, wear is the leading cause of unplanned downtime. Laser cladding extends their life by 300% compared to untreated surfaces."
