Explore our top-performing CE-certified plasma and laser cladding equipment engineered for heavy-duty metal surfacing.
In modern industrial applications, bearings, rotary shafts, valves, and mechanical couplers (often translated as "rodamiento automático" assemblies in Spanish-speaking manufacturing sectors) face relentless tribological wear, oxidation, and mechanical shear. Relying on simple metallurgical components is no longer viable. Today's global industry relies on CE-certified automatic plasma and laser cladding systems to deposit high-performance powder coatings—such as cobalt-based Stellite, nickel alloys, and tungsten carbide matrices—directly onto high-wear surfaces.
By leveraging an automated PTA (Plasma Transferred Arc) or laser cladding platform, manufacturers achieve a dilution rate of less than 5%, ensuring that the chemical properties of the expensive overlay material remain uncompromised while metallurgical bonding with the substrate stays perfectly intact.
For European and global procurement managers, the safety and compliance of heavy industrial machinery are paramount. Under European Directive 2006/42/EC (Machinery Directive), our equipment is fully certified under the Certificación CE framework. This ensures that every automatic cladding unit, manipulator positioner, and laser hardening machine integrates robust electromagnetic compatibility (EMC), low-voltage safety barriers, dual-hand control overrides, and isolated laser-housing modules to protect personnel and satisfy strict regional environmental audits.
Shanghai Duomu has been a leading manufacturer and exporter of PTA cladding machine and Laser cladding machine for more than ten years with a strong technical background.
Our dedicated technical department features an independent R&D team, which develops, produces and sells plasma cladding machine equipment. The welding machine has stable performance and can maintain efficient long-term operation. In addition, the laser cladding equipment sold by the company can effectively support large-scale remanufacturing projects. We have mature technological means to provide complete sets of industrial equipment solutions.
At present, the company's products have penetrated into many fields such as aerospace military industry, nuclear power, petrochemical industry, coal mines, metallurgy and forging, agriculture, water conservancy and electric power, etc.
By placing production and customization inside China's leading metallurgical processing hub in Shanghai, Shanghai Duomu leverages local high-tech clusters and optimized supply chains. This allows us to offer unbeatable lead times, high R&D output, and highly customized automation integrations that Western competitors struggle to match at the same price point.
Global procurement teams prioritize our machinery because we supply not just standard hardware, but complete integrated solutions—from automatic powder feeders to multi-axis manipulator positioners—reducing installation bottlenecks and speeding up time-to-market.
We can provide customized equipment, automatic laser cladding equipment, automatic plasma cladding equipment, intelligent robot cladding equipment, etc. according to customers' requirements, including special equipment in the industry, such as hydraulic rod cladding machine, pick cladding machine, valve cladding machine, etc.
Our commitment: We match your specific wear parameters (hardness, corrosion levels, temperature thresholds) to configure the optimal power source, powder feed rates, and CNC positioning coordinates.

How automation and modern metallurgy are altering global maintenance, repair, and overhaul (MRO) strategies.
Modern cladding systems increasingly incorporate active visual sensors. Real-time path adjustments correct for component deviations during long-run automatic bearing surfacing, ensuring consistent weld heights and bead profiles.
By blending the deep penetration of PTA with the high speed and minimal heat input of laser cladding, operators can execute dual-layer hardfacing to achieve crack-free coatings with unparalleled bonding strength.
Rather than scrapping worn components, global enterprises now use localized automated cladding to restore shafts and bearings to original dimensions, slashing carbon footprints and raw material costs by up to 75%.
Read detailed experiences from metallurgical engineers and operational managers using Shanghai Duomu cladding solutions.
“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 industries such as petrochemical, power generation, and chemical processing scale up temperatures, having a reliable machine makes all the difference.”
Valve Manufacturing Director
“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 delays. Standardizing on Duomu's PTA cladding has extended our screw conveyor service life by 3.5 times.”
Head of MRO, Mining Group
“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. Shanghai Duomu machines give us precise control over the arc profile to keep dilution consistently below 5%.”
Metallurgical QA Lead
“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 overall bottom-line efficiency. The investment in automated laser cladding equipment returned its capital cost in less than 9 months.”
Procurement Manager
“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. We switched from manual stick welding to Shanghai Duomu's automatic DQF-LC602 double-station ball valve cladding equipment. The surface finish is so consistent that it reduced our subsequent grinding and CNC machining time by 40%.”

Detailed information on CE certification compliance, automated cladding configurations, and component compatibility.
CE certification (Certificación CE) confirms that the equipment complies with the fundamental health, safety, and environmental standards of the European Economic Area. This includes strict requirements for electrical isolation, industrial laser housing isolation (Class 1 laser safety standards), emergency cutoff speed, and EMC noise emission suppression, allowing rapid commissioning in global industrial facilities.
Automatic bearing cladding uses continuous CNC controls synchronized with rotary positioners to overlay bearing surfaces and seats. Standard cladding is typically manual or semi-automated. By automating, the heat input is perfectly controlled to prevent thermal distortion of the bearing's geometric tolerance, ensuring the final component meets high concentricity requirements.
Our systems handle a broad spectrum of atomized alloy powders, including Cobalt-based alloys (Stellite series for extreme high-temp hardness), Nickel-based alloys (for complex corrosive chemicals), and Iron-based alloys (for cost-effective wear protection), as well as heavy-duty Tungsten Carbide (WC) mixtures for mining drill bits and screw feeders.
Laser cladding generally produces the lowest dilution rate (often under 2-3%) due to its extremely concentrated heat source. PTA cladding achieves a dilution of around 5-8%, which is still significantly lower than MIG/TIG welding processes (which run at 15-30% dilution). This keeps the cost of base materials low and increases chemical purity on the outermost wear layer.
