Explore our premium range of industrial-grade laser cladding systems, plasma powder surfacing machines, and custom weld torches. Engineered to withstand high-wear, high-temperature, and corrosive working environments.
Modern industrial equipment operations are constantly pushing materials to their physics limits. Extreme mechanical friction, high-velocity particulate erosion, chemical oxidation, and high temperatures act as limiting factors on equipment lifespan. Traditional thermal spraying and conventional hardfacing techniques often lead to severe dilution rates and weak mechanical bonds that degrade prematurely under tension.
Laser Cladding and Plasma Transferred Arc (PTA) cladding technologies stand at the forefront of the circular economy and materials science. By introducing a precisely focused energy source, these techniques deposit premium alloy powders (such as stellite, nickel-based alloys, cobalt-based alloys, and tungsten carbides) directly onto host substrates. This produces a true metallurgical bond with minimal dilution rates and a extremely narrow Heat Affected Zone (HAZ).
Whether you require a complete system installation or tailored cladding engineering configurations, utilizing top-tier automated machine tool integrations provides unprecedented control over metallurgical properties, reducing unplanned industrial downtime and material replacement costs by up to 80%.
At present, our products and cladding solutions have penetrated into many critical engineering sectors globally, proving their durability and efficiency in the most demanding conditions.
Beyond our primary industries, we have engineered tailored cladding architectures for sectors including: nuclear power generation, where material purity and microstructural integrity are safety-critical; petrochemical processes, requiring severe erosion-corrosion resistant overlays; coal mining extraction, featuring abrasive sand and high contact stresses; and water conservancy / electric power distribution, protecting critical hydraulic components against cavitation wear.
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 and highly experienced technical background. We house an independent R&D team that develops, produces, and sells advanced plasma cladding machine equipment globally.
Our cladding solutions are designed for ultra-stable performance and can maintain efficient, continuous operation over extended shifts in harsh industrial environments. Our specialized laser cladding systems effectively support large-scale remanufacturing projects. By deploying mature, verified technological platforms, we deliver complete sets of industrial equipment solutions designed for instant integration.
At Shanghai Duomu, we align our product architecture with emerging market needs and next-generation production processes.
High-capacity double column gantry architectures built to support multi-axis robotic movements with micrometer-level positioning accuracy.
Systems featuring advanced co-axial powder feed mechanisms allowing functionally graded layers to transition seamlessly between materials.
Integrating infrared thermal monitoring cameras and AI-driven feedforward systems to control laser power dynamically and avoid overheating.
The roadmap of Duomu includes upgrading to ultra-high-speed laser cladding (EHLA), which allows deposition rates up to 10 times faster than conventional methods. This advance is critical for processing large rotationally symmetric components like hydraulic cylinders and rotor shafts, bringing cladding cycles in line with traditional grinding workflows.
Additionally, we are expanding our modular plasma and laser configurations. Clients can hot-swap cladding heads on the same machine platform to transition between high-deposition PTA cladding and high-precision laser surface melting, ensuring unmatched flexibility on the factory floor.

"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 performance."
"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, abrasive wear, and sand erosion."
"Optimizing the mechanical properties of wear-facing overlays requires deep knowledge of base-metal metallurgical compatibilities. Control thermal dissipation to avoid cracking."

Get answers to common technical inquiries about Laser Cladding and PTA (Plasma Transferred Arc) processes.
Laser Cladding uses a focused laser beam as the heat source, delivering a highly concentrated energy zone, minimal heat input, and a very narrow Heat Affected Zone (HAZ), making it ideal for precision parts. PTA (Plasma Transferred Arc) cladding uses a plasma arc as the energy source, offering higher deposition rates and lower equipment costs, suitable for thick wear plate overlays and large valves.
The dilution rate is the percentage of host substrate material that melts and mixes into the cladding alloy. Lower dilution rates (below 5%) ensure that the deposited clad layer retains its designed wear and corrosion properties without being degraded by the base metal chemistry.
Yes. Our systems feature flexible powder feeders capable of processing iron-based, nickel-based, cobalt-based (such as Stellite), and tungsten carbide composite powders, letting operators customize wear characteristics.
Cracking is mitigated through controlled thermal management. This includes preheating the substrate when necessary, selecting compatible transition buffer layers, controlling cooling rates, and optimizing laser or plasma heat inputs.
Yes, our solutions include intelligent robot cladding systems. We integrate industrial robotic arms (such as our DH1440-B06 Automatic plasma surfacing robot) to automate complex trajectories and 3D surface cladding profiles.
