In the era of Industry 4.0, the demand for sustainable manufacturing and asset life extension has propelled Laser Cladding (レーザークラッティング) and PTA (Plasma Transferred Arc) welding to the forefront of surface engineering. As a leading manufacturer with over a decade of technical expertise, Shanghai Duomu is redefining how heavy industries approach wear, corrosion, and thermal fatigue.
Laser cladding technology provides a metallurgical bond with minimal dilution and a small heat-affected zone (HAZ), making it superior to traditional thermal spraying or arc welding. This "Information Gain" in manufacturing allows for the repair of high-value components such as aerospace turbine blades, hydraulic rods, and mining screw conveyors with precision that was previously impossible.

Enhancing tool durability against soil abrasion.
Critical component repair with zero-tolerance precision.
Corrosion-resistant overlays for deep-sea drilling.
Extending the life of molds and forging dies.
"The PTA Welding Valve Application Guide is not just a process choice for valve manufacturers facing high wear, but also a key path to improving product competitiveness."
"In mining and cement, screw conveyors are frequent causes of unplanned production downtime. Our cladding solutions drastically reduce this risk."
"One of the most critical factors that directly affects overlay performance is the dilution rate. Shanghai Duomu machines maintain industry-leading control."
As we look toward 2030, our R&D is focused on AI-Integrated Monitoring. Future systems will feature real-time melt pool analysis, automatically adjusting laser power and powder feed rates to ensure 100% defect-free cladding. We are also expanding our Mobile Laser Cladding units for on-site repairs in remote mining and offshore locations, minimizing logistics costs for our clients.
Integration of 6-axis and 7-axis robotic arms for complex geometry cladding.
Developing ultra-high-speed laser cladding (EHLA) for rapid surface covering.
Customizing alloy powders with nano-structures for extreme environment resistance.
Laser cladding offers a much smaller heat-affected zone and lower dilution (typically <5%), which preserves the base material's properties and allows for higher precision on delicate parts.
