Explore our premium machinery range engineered to execute precision surface engineering, high-integrity cladding, and automated structural fabrication.
In modern heavy manufacturing, the prevention and restoration of oxidized structures—traditionally referred to as Laser Ruggine (Laser Rust Removal and Surface Preparation)—have transitioned from experimental technologies to industry imperatives. Globally, carbon steel, alloy matrices, and heavy equipment lose billions in asset value annually due to oxidative wear and surface corrosion.
In contrast to chemical acid pickling or abrasive sandblasting, which carry strict environmental liabilities and pose occupational safety hazards, high-power fiber laser cleaning systems utilize precise optical ablation to strip away oxides, rust, paint, and organic films without altering the base material’s mechanical properties. As structural integrity standards rise in industries like high-speed rail, automotive chassis fabrication, and aerospace turbine manufacturing, China-based manufacturers have built robust, cost-effective industrial solutions. These systems combine high-peak-power pulsed lasers with multi-axis automated tooling to support both restorative remanufacturing and pre-welding surface preparation.
Zero chemical effluents, minimal power usage, and zero hazardous waste disposal fees.
Sub-nanosecond pulse control avoids thermal distortion, protecting delicate alloys.
Pre-weld laser ablation ensures porosity-free weld seams and high mechanical shear strength.
Easily integrates with industrial gantry robots for repeatable, inline manufacturing.
Understanding the micro-level thermodynamic interactions during laser rust removal and metal cladding.
Our high-frequency pulsed laser systems emit short, high-energy pulses that create intense thermoelastic stress waves. This mechanism vaporizes oxide layers instantly while maintaining a heat-affected zone (HAZ) close to zero.
By introducing alloy powders (such as Stellite, Inconel, or tungsten carbide matrices) into the path of a high-power diode or fiber laser, our machines achieve complete metallurgical bonding with low dilution rates (<5%).
Equipped with proprietary CNC and PLC processors, our systems map intricate geometries dynamically. This capability ensures uniform layer thickness and consistent coating profiles across complex workpieces like screw conveyors and hydraulic rods.

Explore Our Full RangeOur surface engineering systems support critical applications in major industrial sectors worldwide.
How laser cleaning and surface engineering solve critical engineering challenges across industries.
Components operating in mines—such as continuous miner cutter heads, dragline bucket teeth, and heavy screw conveyors—suffer from severe abrasive wear and impact damage.
By integrating automated Plasma Transferred Arc (PTA) cladding and laser surface hardening, we apply thick protective coatings of tungsten carbide or iron-based alloys. This extends the service life of these high-wear components by up to 300% compared to untreated surfaces.
Industrial valves and downhole drilling tools endure corrosive chemicals, high pressures, and high temperatures.
Our automated ball valve welding equipment (such as the DQF-LC602) applies corrosion-resistant superalloys directly to sealing surfaces. Precise dilution control ensures the protective layer retains its corrosion-resistant properties without contamination from the base metal.
We maintain an independent R&D team that develops, produces, and sells plasma cladding systems and laser cleaning equipment. Engineered for long-term operational stability and high efficiency, our systems support large-scale industrial remanufacturing and hardfacing projects. Through mature technological processes, we deliver complete turn-key industrial solutions tailored to your production demands.

Practical guidance on process selection and quality parameters in PTA and Laser Cladding.
"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 offshore drilling demand longer MTBF (Mean Time Between Failures), applying specialized cladding layers is essential."
"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. Automated cladding of screw flights ensures continuous output and extends conveyor lifecycle."
"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. Minimizing dilution preserves the corrosion and wear properties of the deposition layer."
Exporting high-precision, high-power laser cleaning and PTA cladding systems requires strict adherence to international safety and quality standards. Our manufacturing facilities are fully certified to ISO 9001:2015, ensuring traceabilty and quality control across every production stage.
All laser cleaning (Laser Ruggine) systems export-ready for Europe and North America carry standard CE Markings and comply with international laser safety standards, including IEC 60825-1 for Class 4 laser products. This compliance ensures safe operation through interlocked enclosures, emission indicators, and dedicated safety shutoff modules.
To support our global customers, we partner with specialized industrial agents across Europe, Southeast Asia, and the Americas. This network allows us to provide responsive local support, rapid spare parts supply, and remote diagnostic assistance. We help our customers maximize machine uptime and maintain high productivity.
Developing next-generation surface engineering systems with closed-loop process monitoring and real-time defect detection.
Future system iterations will integrate real-time optical sensors and machine learning algorithms. By monitoring the melt pool's temperature profile dynamically, the machine automatically adjusts laser power, scan speed, and powder feed rates. This real-time control maintains a constant coating quality, even when processing substrates with variable thicknesses.
We are designing comprehensive digital twin platforms for our automated gantry systems. This technology allows operators to simulate and refine laser scanning paths virtualized on 3D CAD data before executing the process on physical components. This reduces setup times and minimizes material waste during short-run production.
For advanced rust and oxide removal, we are developing hybrid laser sources that combine deep-ultraviolet (UV) and near-infrared (IR) wavelengths. This system will combine the fast thermal expansion of IR lasers with the high chemical bond ablation of UV lasers, allowing operators to clean complex composite materials and high-strength steels faster.
