Explore our top-performing industrial automatic plasma cladding systems, precision laser welding tools, and robotic positioning units.
In the modern era of heavy manufacturing, surface engineering, and robotic welding integration, the roles of Manipulateurs Et Positionneurs (Manipulators and Positioners) have transitioned from simple auxiliary fixtures to critical coordinates in multi-axis automation cells. High-precision industries, including aerospace, petrochemical, nuclear power, and marine engineering, demand strict component geometry maintenance, structural consistency, and minimal metallurgical distortion.
Globally, the market is shifting toward total closed-loop digital synchronization. When coupled with advanced thermal processes like Plasma Transferred Arc (PTA) cladding and multi-kilowatt Laser Cladding, positioners must execute micro-step rotation and tilt actions with zero backlash. Any minor speed variation can lead to fluctuations in weld pool dilution, causing high rejection rates in severe-service components such as downhole drilling subs, hydraulic cylinder rods, and power generation turbines.
By integrating advanced servo systems, dynamic load balancing, and real-time CNC communication protocols, modern Manipulateurs Et Positionneurs minimize cycle times while optimizing the angle of deposition. This ensures that gravity works in favor of the welding puddle, yielding highly uniform overlay tracks and robust metallurgical bonds.
Shanghai Duomu has been an industry-defining manufacturer and exporter of PTA cladding machines, Laser cladding machines, and integrated positioning manipulators for more than ten years. Bolstered by a strong technical background and a dedicated R&D team, our domestic production facilities leverage China's unparalleled industrial supply chain to achieve rapid customization, precision machining, and strict quality control.
Traditional Western systems often carry high premium markups and prolonged design lead times. In contrast, Chinese manufacturing ecosystems offer quick access to high-grade steel castings, advanced sensor integrations, and raw electronic components. This allows Shanghai Duomu to design, test, and ship tailored welding positioners and robotic manipulators in a fraction of the time.
Our independent R&D team continuously refines current control systems and powder delivery mechanisms. Whether you require standard modular units or complete industrial solutions (like integrated hydraulic rod cladding machines, pick cladding machines, or valve cladding machines), Duomu delivers long-term stability and high cost-efficiency, ensuring your facility sustains a higher return on investment.
Our advanced cladding machinery and positioning manipulators are deployed across a vast array of demanding global industries.
Exploring the future of multi-axis weld deposition and automated surface engineering.
Integrating servo motors with EtherCAT protocols links the rotation of the positioner directly with the torch motion of the manipulator. This maintains constant linear cladding speed over non-cylindrical workpieces, ensuring a uniform hardfacing thickness.
With global carbon targets, industries prefer repairing worn surfaces over replacing complete assemblies. Multi-axis cladding on positioners can apply metallurgical overlays that outlast the base steel by up to 300%, reducing resource demand.
Real-time sensory feedback monitors the molten pool temperature. By dynamically adjusting the angle of rotation, the molten metal is kept stable, preventing core metal dilution and preserving the chemistry of the overlay alloy.
Detailed technical answers to help buyers evaluate automated cladding equipment.
Dilution refers to the percentage of base metal that melts and mixes into the deposited cladding alloy layer. In severe working environments, a high dilution rate dilutes the hard phase particles (like tungsten carbides or chromium carbides) or corrosion-resistant elements (like nickel and cobalt). This degrades the surface performance. Advanced positioning setups allow consistent control of arc power and travel speed to keep the dilution rate under 5%.
Manipulating massive, awkwardly shaped workpieces manually presents safety risks and takes time. By utilizing heavy-duty positioning turntables and dynamic column-and-boom manipulators, the workpiece is mechanically locked and rotated under program control. This minimizes manual overhead rigging, prevents hoisting accidents, and reduces operators' exposure to intense heat, welding radiation, and metal fumes.
PTA (Plasma Transferred Arc) cladding uses a high-density, transferred arc plasma as a heat source to melt both the substrate surface and the alloy powder feeding into it. It is known for high deposition rates, deep penetration, and structural reliability. Laser Cladding uses a concentrated laser beam as the thermal source, offering low heat input, a very small Heat Affected Zone (HAZ), minimal dilution rates (often under 2%), and high dimensional precision. This makes it ideal for delicate parts like turbine blades.

Discover how global heavy industrial manufacturers benefit from Duomu's cladding systems.
"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. As petrochemical and oil & gas industries expand, using these systems on positioners has minimized our scrap rate."
Petrochemical Valves Manufacturer
"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. Using Duomu's automatic screw welding machine helped us double conveyor lifespan."
Cement & Mining Heavy Machinery
"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 require corrosion resistance or high carbide content, matching the right positioner rotation speed is key."
Surface Hardfacing Institute
"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 optimization. The gantry laser cladding system we integrated has run 24/7 without issues."
Power Generation & Heavy Industry
"Industrial valves are constantly exposed to severe operating conditions: high pressure, extreme temperatures, corrosive media, and sand erosion. Our transition to automatic plasma cladding systems from Duomu, using a synchronized positioner, allowed us to lay down a protective coating with negligible porosity and high bond strength."
