Discover our advanced range of automated plasma cladding systems, precision laser hardfacing platforms, and specialized torch systems configured for global industrial exports.
As modern aerospace structures push the limits of speed, altitude, and thermal resistance, traditional welding processes are being replaced by highly precise cladding systems. From Plasma Transferred Arc (PTAW) to multi-axis automated laser metal deposition, China is emerging as a global center of excellence for aerospace cladding systems.
Thermal fatigue, oxidation, and cavitation resistance are critical in high-pressure aerospace parts. Our cladding technology deposits metallurgical coatings with minimal dilution rates, protecting critical nickel, titanium, and cobalt superalloys in challenging operating environments.
Traditional arc welding introduces extreme heat, causing grain growth and thermal distortion. Advanced laser and PTA systems limit the Heat Affected Zone (HAZ), maintaining the microstructural integrity of underlying aerospace alloys while achieving near-net-shape deposition.
By using multi-axis CNC gantries, synchronized positioners, and closed-loop optical feedback systems, we ensure consistent coating thickness, eliminate internal voids, and deliver predictable microstructures for high-value applications.
Shanghai Duomu has been a leading manufacturer and exporter of PTA cladding machines and Laser cladding machines for more than ten years, supported by a strong technical background. Our dedicated team develops, produces, and sells plasma cladding systems built to run continuously in challenging industrial environments.
Our technologies support demanding remanufacturing applications globally. By combining advanced electrical design, robust mechanical execution, and software integration, we deliver turnkey solutions for precision overlay welding across major industries.
We operate an independent R&D center focused on plasma arc dynamics and laser material interactions. Our machines feature stable power sources and intelligent control logic to handle long-term production. Our technologies support large-scale industrial remanufacturing projects with mature engineering solutions.
Our design capabilities range from custom gantry architectures to specialized multi-axis positioning systems, ensuring high precision when working with challenging materials.
Our products are used across critical global industries, including aerospace military applications, nuclear power generation, petrochemical processing, coal mining, metallurgy, agriculture, and water conservancy.
We supply custom machinery tailored to customer requirements. Our range includes automatic laser cladding platforms, automatic plasma cladding systems, and intelligent robotic installations for high-precision components like hydraulic rods, mining picks, and control valves.
Both Plasma Transferred Arc Welding (PTAW) and Laser Cladding (LC) are used for high-performance surface modifications, but they suit different engineering requirements:
Dilution rate is the mixing of the substrate material with the cladding alloy. In aerospace applications, controlling dilution is crucial. If dilution is too high, the substrate elements (such as iron in steel) can migrate into the cobalt or nickel cladding overlay, reducing its wear and corrosion resistance.
Our automated PTA and Laser systems maintain dilution levels below 3% (and under 1% for laser configurations). This helps preserve the mechanical properties of materials like tungsten carbide (WC-Co) and nickel-chromium-boron-silicon (NiCrBSi) alloys.
Consistent powder feeding is essential for high-quality cladding. Standard gravimetric feeders can suffer from pulsation, leading to variations in the cladding layer. Our technical department has developed integrated powder feeders with digital closed-loop controls, ensuring smooth delivery of superalloys under varying chamber pressures.
We work with your engineers to tailor machine dimensions, axis count (up to 8-axis robotic systems), software controls, and power supplies to integrate with your existing manufacturing configurations.
Every system undergoes rigorous testing, including laser alignment, structural load tests, and test runs under full production conditions. Our equipment conforms to international CE and ISO safety standards.
With built-in network interfaces, our engineers can access diagnostic data remotely. This allows us to resolve setup issues, adjust software parameters, and provide guidance without on-site delay.

"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 industries such as mining, cement, power generation, steelmaking, chemical processing, and biomass energy, screw conveyors are often regarded as auxiliary equipment. However, maintenance data shows that they are among the most frequent causes of unplanned production downtime."
"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."
"In industries such as Oil & Gas, Mining, Power Generation, Cement, and Heavy Equipment Manufacturing, hardfacing is no longer just a repair process. It has become a critical technology directly related to equipment lifespan, downtime costs, maintenance frequency, and process safety."
"In industries such as oil & gas, petrochemical, power generation, mining, and marine engineering, industrial valves are constantly exposed to severe operating conditions including high pressure, extreme temperatures, corrosive media, and abrasive wear."
