A Comprehensive Technical Whitepaper on Laser Cladding, PTA Welding, and Custom Surface Engineering Solutions from Shanghai Duomu.
Лазерная наплавка, universally known in the mechanical engineering domain as Laser Cladding, is a revolutionary additive manufacturing technique. By focusing a high-energy laser beam on a substrate material, a localized molten pool is generated. Alloy powder (or wire) is simultaneously fed into this melt pool, rapidly cooling down to form a highly dense metallurgical bond with an exceptionally low dilution rate (<5%).
Unlike traditional thermal spraying or arc welding processes, laser cladding minimizes thermal distortion, preserves the chemical composition of the substrate, and provides superior wear, corrosion, and erosion resistance. This makes it a critical technology for repairing expensive industrial assets, extending service lifetimes, and enabling high-performance local surface modifications on cost-effective base alloys.
China has emerged as the global epicenter for industrial-grade laser cladding and Plasma Transferred Arc (PTA) machinery production. Shanghai Duomu, leveraging more than ten years of robust technical background, leads the industry in manufacturing high-efficiency equipment.
The Chinese supply chain advantages are not merely about lower production costs; they represent a deep ecosystem of technological integration. From direct access to spherical atomized alloy powders (Ni-based, Fe-based, Co-based, and tungsten carbide matrices) to the localization of high-precision fiber lasers and multi-axis CNC gantries, China manufacturers deliver state-of-the-art machinery at unmatched speeds.
For instance, systems like the DLM-LC501 Double Column Gantry Welding System and custom manipulator positioners highlight our capability to handle heavy-duty components such as hydraulic mining columns, large screw brick extruders, and complex aerospace parts with micro-level accuracy.
Shanghai Duomu has been a leading manufacturer and exporter of PTA cladding machines and Laser cladding machines for more than ten years, built on a rock-solid technical background.
We design, develop, and export complete turn-key industrial solutions. By blending automation, custom-engineered cladding heads, and advanced power sources, we help global manufacturing companies achieve unparalleled structural durability.

Stay ahead of technological transitions. Explore why global enterprises are turning to automated hybrid cladding structures.
The transition from conventional laser cladding to Extreme High-Speed Laser Cladding (EHLA) is defining the new era. EHLA allows powder interaction above the melt pool, melting it before contact, which yields deposition speeds 10 to 100 times faster. This dramatically reduces thermal stress and enables thin coatings down to 20 microns at speed.
Modern manufacturing demands intelligent automation. Integrating multi-axis robots, such as our Laser hardening robot, with specialized rotary positioning tables and custom linear tracks allows complex-shaped geometry overlays (e.g., ball valves, extrusion screws, and curved impeller blades) to be cladded automatically with zero defects.
Selecting the optimal alloy matrix defines the cladding quality. Achieving a high-quality overlay in PTA and laser cladding requires minimizing the dilution rate to prevent substrate elements from degrading the properties of the protective coat. This ensures the hardfacing layer retains full wear and corrosion resilience.
Sourcing laser cladding and PTA machinery internationally demands strict compliance and reliable after-sales support. Shanghai Duomu guarantees compliance with international safety standards, providing CE, ISO9001, and SGS certifications. We provide comprehensive local documentation and training programs for Russian-speaking regions (CIS/Russia), European countries, the Americas, and Southeast Asia.
Our localized support includes installation services, remote digital troubleshooting, component provisioning (e.g., torches, gas shield covers, powder feeders), and guidance on optimizing material parameters to guarantee that your investment operates with maximum uptime and return on investment.

Laser Cladding utilizes a coherent laser light source to generate the melt pool, yielding a minimal Heat Affected Zone (HAZ), exceptionally low dilution rates (<5%), and precise control over thin coating layers. It is ideal for high-precision components. PTA (Plasma Transferred Arc) uses a plasma arc as the heat source. While it has a slightly higher thermal input, it provides much higher deposition rates (up to 10 kg/hr or more) and is extremely cost-effective for thick, heavy-duty protective layers on massive parts like mining buckets, crushing rollers, and large-bore valves.
We integrate advanced PLC systems and robust feedback controllers that coordinate the powder feeding rate, arc current, travel speed, and gas shielding flow in real-time. By optimizing the specific thermal input energy per unit length, we restrict the penetration into the base substrate to guarantee a minimal dilution rate, maximizing the functional properties of the cladding material.
