High-efficiency protective overlay machines built to withstand wear, corrosion, and extreme thermal environments.
An engineering analysis of wear protection and remanufacturing demands in the Russian Federation's industrial hubs.
Moscow and its surrounding industrial belt (including Podolsk, Serpukhov, and Elektrostal) host a highly concentrated cluster of heavy engineering, aerospace, petrochemical, and construction machinery enterprises. With the ongoing pressure for domestic import substitution and the optimization of mechanical asset lifespans, local industries are shifting from costly part replacement cycles to advanced **remanufacturing technologies**.
Components such as extrusion screws in Moscow’s polymer plants, shale oil drilling stabilizers, high-pressure valves, and large-scale agricultural tines face extreme abrasion and chemical corrosion. Standard welding overlays often suffer from high dilution and thermal distortion, leading to premature cracking. Our specialized **Plasma Transferred Arc (PTA) welding** systems serve this region by depositing highly wear-resistant cobalt-based (Stellite), nickel-based, and tungsten carbide composite powders onto critical workpieces with minimal heat-affected zones (HAZ).
For engineering decision-makers and procurement directors in Moscow, selecting the right metallurgical bonding process is critical. Plasma Transferred Arc (PTA) cladding offers a distinct metallurgical bond with a low dilution rate (typically between 3% to 8%), ensuring the pure properties of the alloy powder are maintained even in the first layer. Compared to traditional Submerged Arc Welding (SAW) or manual metal arc cladding, PTA produces a smoother surface finish and a significantly higher deposition rate (up to 12 kg/hr), which directly translates to reduced post-weld machining costs.
Conversely, for precision components such as aerospace turbine blades and micro-valves, **Laser Cladding** serves as the optimal route due to its ultra-low heat input and dilution rates below 1%. Our engineering team provides custom PTA and laser hybrid solutions, offering Moscow’s metalworking facilities the precise balance between production throughput and dimensional stability.
Shanghai Duomu has been a leading manufacturer and exporter of PTA cladding machines and Laser cladding machines for more than ten years with a strong technical background. Equipped with an independent R&D team, we develop, produce, and sell high-stability plasma cladding equipment that maintains efficient long-term operation.
In addition, our laser cladding systems effectively support large-scale remanufacturing projects. We have mature technological means to provide complete sets of industrial equipment solutions, helping our partners across Moscow and worldwide minimize down-time and secure their processing lines.

Leveraging smart manufacturing, multi-axis automated control, and direct-to-enterprise logistics.
At our state-of-the-art facility, we implement **Industry 4.0 standards** for PTA and Laser cladding system fabrication. Each machine undergoes strict mechanical stress relief testing, precision laser alignment, and PLC software optimization. By keeping critical components designed and assembled in-house, we eliminate external supplier bottlenecks. For procurement directors based in Moscow, this means a reliable supply chain with guaranteed parts availability and system customizations that can be finalized in weeks rather than months.
Our automation systems integrate multi-axis robotic arms with positioners, allowing complex 3D profiles (such as industrial screws and non-symmetrical valve bodies) to receive consistent coatings. The resulting reduction in powder waste and energy utilization allows Shanghai Duomu to pass cost advantages directly to our international clients.
Seamless integration, customs clearance, and technical deployment in the Russian Federation.
Exporting high-technology machinery to Moscow requires rigid adherence to customs procedures and regulatory standards. Shanghai Duomu supports our Moscow clients with all necessary documentation, including Customs Union (EAC) compliance declarations, packing lists, and detailed technical specifications in both English and Russian. We partner with reliable heavy cargo logistics networks to coordinate rail and road transport via established cross-border routes, ensuring safe transit and scheduled delivery.
We understand that system downtime is not an option. Our technical team offers comprehensive virtual installation guidance, remote diagnostic integration (enabling online PLC debugging via secure networks), and structured training manuals for local operators. We also cooperate with seasoned technical representatives to support commissioning, calibration, and torch consumables provisioning for our machinery in Moscow.
We can provide customized equipment, automatic laser cladding equipment, automatic plasma cladding equipment, intelligent robot cladding equipment, etc. according to customers' requirements.

Real feedback and process applications from our field specialists and global partners.
"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 and thermal power in Moscow escalate their specs, Duomu's PTA systems provide the exact metallurgical properties we need."
Valve Refurbishing Plant, Moscow Region
"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 shutdowns. Applying PTA cobalt overlays has extended our conveyor lifetime by 3x."
Heavy Mining Machinery Center
"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 need to control low dilution on base materials or ensure high bond strength, Duomu's PLC systems make it simple."
