In the era of Industry 4.0, the longevity and reliability of critical mechanical components are paramount. Laser Hardfacing (also known as Laser Cladding or Laser Metal Deposition) has emerged as the definitive solution for high-precision surface enhancement. Unlike traditional PTA (Plasma Transferred Arc) or thermal spraying, Laser Hardfacing offers a minimal Heat Affected Zone (HAZ), a 100% metallurgical bond, and extremely low dilution rates (<5%).
The global laser cladding market is projected to reach USD 750 million by 2028. Leading manufacturers in Germany, China, and the USA are shifting focus from simple repair to "Additive Manufacturing for Surface Enhancement," driven by the need for sustainable remanufacturing and carbon neutrality.
Our custom laser hardfacing systems utilize fiber laser sources with high beam quality. This allows for precise control over the solidification rate, resulting in a fine-grained microstructure that exhibits superior wear, corrosion, and oxidation resistance compared to bulk materials.
Operating under ISO 9001:2015 frameworks, our equipment and processes comply with international welding standards such as AWS D17.1 and specialized petrochemical norms. We provide full traceability and NDT (Non-Destructive Testing) validation for every project.
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 independent R&D team develops, produces, and sells plasma cladding machine equipment that maintains efficient long-term operation even in the most demanding environments.
We provide complete sets of industrial equipment solutions, effectively supporting large-scale remanufacturing projects. Our mature technological means ensure that every machine delivered meets the highest performance criteria for precision and stability.
Hardfacing plowshares, harvesters, and tilling tools with tungsten carbide alloys to extend service life by 300% in abrasive soil conditions.
Precision laser cladding for turbine blade repair and engine component refurbishment, ensuring zero deformation and maximum safety compliance.
Cladding of drill stabilizers, mud pump valves, and blowout preventer components against erosion and H2S corrosion.
Hot-work die repair and continuous casting roller restoration, significantly reducing downtime in steel mills.
Moving from 3-axis to 6-axis robot-arm integration for cladding complex geometries such as internal bores and spiral shafts.
Implementing real-time melt pool monitoring systems that use AI to adjust laser power and powder feed speed dynamically for zero-defect surfaces.
Combining additive laser cladding with subtractive CNC machining in a single cell to produce finished components from scratch or repair.
We provide customized equipment according to customers' requirements, including special equipment for hydraulic rods, picks, and valves.
A: Laser Hardfacing provides a much lower dilution rate (under 5% vs 15% for PTA), meaning the surface alloy properties are preserved better. It also produces much less heat distortion, making it ideal for precision parts.
A: Yes, we offer specialized internal bore laser cladding heads capable of reaching deep inside cylinders and pipes with diameters as small as 100mm.
A: We support a wide range of powders, including Cobalt-based (Stellite), Nickel-based, Iron-based alloys, and Tungsten Carbide (WC) composites.
A: Absolutely. We provide 24/7 online technical assistance and can deploy engineers globally for on-site installation, commissioning, and staff training.
