Explore our premium range of automated laser cladding, plasma arc welding systems, and high-performance powder feeders designed to extend equipment lifespan.
In the demanding landscapes of modern heavy industries, critical components face aggressive wear, corrosion, and thermal degradation. Traditional repair methods, such as manual arc welding or thermal spraying, often fail to meet the strict quality standards required for high-stress applications. This is where custom laser cladding and Plasma Transferred Arc (PTA) cladding technologies offer a transformative advantage.
By utilizing a high-density energy source, laser cladding precisely deposits a layer of specialized alloy powder onto the substrate. This creates a superior metallurgical bond with minimum dilution rates, ensuring outstanding surface performance while preserving the core mechanical properties of the base metal.

Across key industrial hubs in North America, Europe, and Asia-Pacific, procurement managers are increasingly shifting their focus from short-term component replacement to long-term lifecycle optimization. High-value parts used in oil exploration, petrochemical refining, aerospace propulsion, and steel casting cannot tolerate unexpected downtime.
As global manufacturers seek to minimize environmental footprints and operational expenditures (OPEX), remanufacturing via laser and PTA cladding has emerged as a key strategy. The ability to repair and surface complex, expensive materials—like nickel-based superalloys, cobalt alloys, and tungsten carbide composites—enables businesses to achieve both economic and ecological sustainability goals.
Shanghai Duomu has been a leading manufacturer and exporter of PTA cladding machines and Laser cladding machines for more than ten years. Backed by a strong technical team and deep academic background, we focus on engineering reliable, state-of-the-art additive manufacturing systems.
Our manufacturing processes adhere to the highest international standards, ensuring that every system we build delivers exceptional stability and precision. From initial consultation to final commissioning, Shanghai Duomu is committed to providing global clients with complete industrial surfacing solutions.
Our cladding solutions are designed for demanding operational conditions across multiple key global industries.
We house an independent R&D team that designs, develops, and builds our proprietary plasma cladding equipment. Our welding power sources and mechanical systems are optimized for high-duty-cycle, long-term operations in industrial environments.
Furthermore, our high-power laser cladding systems support large-scale remanufacturing projects. By using integrated sensors, closed-loop powder-feed systems, and automated robotic trajectories, we help clients reduce scrap rates and achieve highly consistent results.
The manufacturing landscape has changed. To navigate volatile global markets, procurement divisions require partner manufacturers that offer more than just low unit costs. Modern procurement demands supply chain resilience, technological adaptability, and reliable engineering support.
Shanghai Duomu's production facility implements advanced Factory 4.0 principles. By integrating smart manufacturing workflows, CAD-to-path robotic programming, and optimized inventory controls, we maintain stable lead times even during global shipping disruptions.

"The PTA Welding Valve Application Guide is not just a process choice for valve manufacturers facing high wear, high corrosion, and high-temperature erosion working conditions, but also a key path to improving product competitiveness."
"In screw conveyors, maintenance data shows that they are among the most frequent causes of unplanned production delays. Implementing PTA hardfacing significantly increases operational lifetimes and reduces downtime."
"In PTA hardfacing, achieving a high-quality overlay is not only about selecting the right alloy powder. One of the most critical factors that directly affects overlay performance is controlling the dilution rate."

Laser Cladding uses a focused laser beam as the heat source, offering a very small heat-affected zone, low dilution rates (typically under 5%), and high dimensional accuracy. It is ideal for complex, high-precision components. PTA (Plasma Transferred Arc) cladding uses a constricted plasma arc to melt both the powder and the substrate surface. It is highly cost-effective, offers faster deposition rates, and is ideal for large-scale, heavy-duty wear-facing applications.
By depositing high-performance materials (such as cobalt, nickel, or tungsten carbide composites) only on the areas subjected to heavy wear or corrosion, we create a protective surface layer. This layer protects the cheaper substrate beneath, extending the operational life of components by 2 to 5 times.
Our optimized PTA cladding torches and power supplies are engineered to keep dilution levels between 5% and 10%. This ensures that the properties of the surfacing alloy are fully realized in a single layer, saving material costs and reducing processing time.
