In the demanding landscape of modern metallurgy, Stellite Schweißen (Stellite welding/hardfacing) represents the gold standard for components subjected to extreme mechanical wear, high temperatures, and corrosive environments. As a premier China Stellite Schweißen Supplier & Factory, Shanghai Duomu has spent over a decade perfecting the integration of cobalt-based alloys with advanced automated delivery systems.
Our expertise is rooted in the E-E-A-T principle: Experience in delivering thousands of projects globally; Expertise in Plasma Transferred Arc (PTA) and Laser Cladding; Authoritativeness in technical innovation; and Reliability (Trust) through rigorous quality control and localized support.
The trajectory of hardfacing technology is moving from manual surfacing to ultra-precise, AI-driven cladding systems. Here is how we lead this evolution.
Transitioning from analog to fully digitalized arc control, ensuring dilution rates under 5% for maximum alloy purity.
Implementing EHLA (Extreme High-Speed Laser Cladding) to provide coatings for large hydraulic rods with minimal thermal distortion.
Developing 6-axis robotic cells capable of complex geometry hardfacing, essential for aerospace and nuclear valve components.
Real-time melt pool monitoring and closed-loop feedback systems to predict and eliminate weld defects before they occur.
At present, the company's products have penetrated into many fields such as aerospace military industry, nuclear power, petrochemical industry, coal mines, metallurgy and forging, agriculture, water conservancy and electric power, etc.
Protecting plows, tillers, and harvesters against severe soil abrasion with Stellite-based hardfacing.
High-temperature resistance for turbine blades and engine components using precision plasma surfacing.
Drill stabilizers and valve seats protected against hydrogen sulfide corrosion and sand erosion.
Unlike standard suppliers, we control the entire process from R&D of the cladding torches to the final assembly of CNC-controlled welding stations.
Located in the industrial heart of Shanghai, we leverage the world's most robust electronics and steel supply chain to provide 24-hour turnaround on spare parts.
Whether you need a single custom torch or a full fleet of 20 automated cladding lines, our factory is structured for rapid industrial scaling without loss of quality.
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. We have an independent R&D team, which develops, produces and sells plasma cladding machine equipment.
The welding machine has stable performance and can maintain efficient long-term operation. In addition, the laser cladding equipment sold by the company can effectively support large-scale remanufacturing projects. We have mature technological means to provide complete sets of industrial equipment solutions.
Get in TouchOur Stellite Schweißen solutions are not just machines; they are answers to critical industrial failures. We specialize in "Information Gain" by analyzing the metallurgical failure points of our clients' components.
In nuclear reactors, valve sealing surfaces must withstand high-pressure steam without erosion. Our PTA process applies Stellite 6 with zero porosity, meeting the strictest ASME and RCC-M standards.
For large-scale mining equipment, we provide "remanufacturing" solutions. Instead of replacing expensive shafts, our laser cladding systems restore them to original dimensions with enhanced wear properties.
Continuous casting rolls suffer from thermal fatigue. Our specialized cladding powders and heat-input control systems extend roll life by 300%.
Screw conveyors in biomass plants face organic acids and abrasive fibers. Our automated surfacing machines provide the precise coating thickness needed for these high-torque environments.
"In Plasma Transferred Arc (PTA) hardfacing, achieving a high-quality overlay is not only about selecting the right alloy powder. Dilution rate is the most critical factor..."
"In Oil & Gas, the Real Cost Is Downtime—Not the Component. When a choke valve fails, the response must be a long-term hardfacing fix, not just a replacement..."
"Improving PTA efficiency isn't just speed; it's about the consistency of the deposit and the reduction of post-weld machining time..."
Exporting advanced welding equipment requires more than just shipping. As a global partner, we ensure:
Our equipment complies with CE, ISO 9001, and UL requirements. We provide full documentation for traceability, vital for Aerospace and Nuclear sectors.
Utilizing 5G-enabled IoT modules, our engineers can diagnose and calibrate your cladding machine from our Shanghai headquarters in real-time.
We provide localized training for operators across Europe, North America, and Southeast Asia, ensuring your team masters the art of Stellite hardfacing.
