Advanced machinery engineered to improve performance, extend lifecycle, and reduce operational downtime in mining, oil and gas, and heavy manufacturing.
The Republic of Serbia stands as a major industrial hub in Southeastern Europe. With key sectors like the HBIS Group Iron & Steel plant in Smederevo, the intensive copper and gold mining operations of Zijin Mining in Bor, and the refining infrastructure of NIS (Naftna Industrija Srbije) in Pančevo, the country demands high-reliability mechanical components.
Traditional maintenance strategies, including total part replacement or basic thermal spraying, pose significant costs and delivery challenges. Our specialized laser and plasma transferred arc (PTA) cladding solutions provide a metallurgical bond that extends the operational lifespan of high-wear industrial parts by up to 300%. This technology ensures low dilution rates and minimal heat input, preventing distortion of critical mechanical components.

Read about hardfacing principles, dilution rate studies, and how proper overlay control prevents equipment 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. Whether you need to prevent matrix dissolution or preserve carbide integrity...

Improving PTA hardfacing efficiency is not simply about increasing welding speed or depositing more alloy within a shorter time. In industrial production, the real efficiency of a Plasma Transferred Arc (PTA) hardfacing process depends on energy transfer controls and minimizing metal loss...

In Oil & Gas, the Real Cost Is Downtime—Not the Component. When a choke valve fails due to sand erosion, a mud pump valve seat wears beyond tolerance, or a drill stabilizer reaches the end of its service life, the traditional response is replacement. Learn how PTA cladding restores parts at a fraction of the cost...

For industrial equipment operating in abrasive, erosive, corrosive, or high-temperature environments, wear is inevitable. The real challenge is not preventing wear altogether but choosing the most cost-effective maintenance strategy once wear occurs. Many maintenance teams have saved millions of Euros by shifting to laser surfacing...

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. Laser and PTA cladding extend conveyor lifespans dramatically...

Clear, direct answers regarding mechanical specs, application feasibility, integration logistics, and local engineering compliance.
Our systems support a wide variety of commercial metal powder compositions. For laser cladding, we commonly run self-fluxing nickel-based alloys, cobalt-based alloys (Stellite 6, Stellite 12), iron-based wear-resistant steels, and ceramic composites like Tungsten Carbide (WC-Co/Ni). For PTA, we process standard hardfacing alloy powders with high metallurgical bond strength.
Traditional processes like Submerged Arc Welding or standard MIG often lead to dilution rates of 15% to 30%, which contaminate the cladding alloy with the base metal chemistry. Shanghai Duomu’s laser cladding equipment maintains a low dilution rate of under 5%, preserving the wear and corrosion-resistant properties of the deposited alloy in a single pass.
We provide full logistics planning to Serbia, complete clearance documentation, and remote video commissioning. For complex robotic cells, we can send field service engineers directly to your facilities in regions such as Smederevo, Bor, Belgrade, or Novi Sad for system assembly, parameter tuning, and operator safety training.
