Establishing New Standards in Surface Coating and Material Remanufacturing
Laserauftragschweißen, or Laser Cladding, represents the pinnacle of additive manufacturing for industrial wear protection. As a leading manufacturer with over a decade of technical mastery, Shanghai Duomu integrates high-energy laser beams with precise powder feeding to create a metallurgical bond that is significantly superior to traditional thermal spraying.
Unlike conventional welding, the laser process offers a minimal Heat Affected Zone (HAZ) and extremely low dilution rates (typically < 5%). This allows for the deposition of high-performance alloys—such as Cobalt-based, Nickel-based, or Tungsten Carbide composites—onto economical base metals without compromising the coating's purity or the component's structural integrity.
Bridging the gap between traditional surfacing and AI-integrated production
Integration of 6-axis KUKA/ABB robotics with synchronized external axes for complex geometries like turbine blades and multi-flute screws.
Real-time melt pool temperature monitoring and CCD-based path correction to ensure 100% defect-free coating layers in aerospace applications.
Predictive maintenance and virtual simulation of thermal stresses before the laser hits the metal, reducing trial-and-error costs by 40%.
Engineered reliability for the world's most demanding environments
Enhancing the lifespan of plows and harvesters using localized hardfacing, reducing downtime during peak seasons.
High-precision laser cladding for turbine blade restoration and aero-engine component reinforcement under extreme thermal cycles.
Combatting sand erosion and hydrogen sulfide corrosion in drill stabilizers and valve seats with PTA hardfacing.
Extending the service life of continuous casting rolls and extrusion dies through high-temperature wear-resistant coatings.
Located in the heart of Shanghai's industrial hub, our facility leverages a sophisticated Supply Chain 4.0 model. By integrating independent R&D (Technical Department) with localized raw material sourcing, we offer global clients a unique "Efficiency Advantage."
We understand that global enterprises require more than just a machine. They require a partner who understands international standards (ISO, CE) and local operational needs.

Direct knowledge from our surface engineering laboratories
"In Plasma Transferred Arc (PTA) hardfacing, achieving a high-quality overlay is not only about selecting the right alloy powder or optimizing welding parameters. One of the most critical factors that directly affects overlay performance is the dilution rate. Whether you are surfacing oil & gas valves or mining picks, controlling the mix of base metal and coating is vital for wear resistance."
— Technical Director, Shanghai Duomu"In Oil & Gas, the Real Cost Is Downtime—Not the Component. When a choke valve fails due to sand erosion, the traditional response was replacement. Today, with our Laser Cladding Machine for blades and valves, we offer a remanufacturing solution that outperforms the original part's hardness by 200%."
Addressing the core concerns of procurement and engineering leads
While both provide metallurgical bonds, Laser Cladding offers a smaller HAZ and lower dilution (1-3%) compared to PTA (5-10%). Laser is ideal for high-precision components, while PTA is more cost-effective for large-scale, thick-layer surfacing.
Yes. As showcased in our product catalog, we provide specialized systems like the DLG-LC501 for screws, DQF-LC602 for ball valves, and automated robots for hydraulic rods. Every system can be tailored to your component dimensions and material requirements.
All equipment undergoes a rigorous 72-hour continuous operation test before shipping. We provide a full "Birth Certificate" for each machine, including laser power stability logs and powder feed consistency reports.
We offer a "Hybrid Support" model—immediate 24-hour digital assistance combined with a network of regional service partners for physical maintenance and spare parts supply.
