In the contemporary industrial era, the demand for surface engineering has shifted from basic repair to sophisticated Life Cycle Management (LCM). As a premier cladding welding supplier, we address the global challenge of equipment degradation caused by extreme friction, high-temperature oxidation, and corrosive environments.
Laser and PTA cladding are at the heart of the "Circular Economy." By applying a high-performance alloy layer to worn components, we extend service life by up to 500%, reducing the carbon footprint associated with manufacturing new steel parts.
Our solutions utilize advanced alloy powders—including Tungsten Carbide (WC), Stellite alloys, and Ni-based superalloys—to create metallurgical bonds that far exceed the performance of traditional thermal spraying.
From the deep-sea oil rigs in the North Sea to the mining hubs of Australia, cladding technology is no longer optional—it is a critical requirement for maintaining operational uptime in multi-billion dollar infrastructures.
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 reputation is built on Experience, Expertise, Authoritativeness, and Trustworthiness (E-E-A-T).
I 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.
Protection for plows and harvesting components against high-abrasion soil conditions. Use of Fe-based and WC-based powders to ensure longevity during peak seasons.
Precision repair of turbine blades and landing gear components. Our 6-axis robotic arms ensure the lowest heat-affected zone (HAZ) for safety-critical parts.
Cladding for drill bits, stabilizers, and valves. Enhancing resistance to hydrogen sulfide corrosion and abrasive sand erosion in downhole environments.
Rollers and casting molds benefit from surfacing that resists thermal fatigue and molten metal adhesion, significantly reducing plant downtime.
As a leading cladding welding supplier, we provide insights that go beyond product listings. Understanding the Dilution Rate is the key to quality. In PTA hardfacing, achieving a dilution rate below 5% is critical for maintaining the chemical purity of the alloy layer.
We can provide customized equipment, automatic laser cladding equipment, automatic plasma cladding equipment, intelligent robot cladding equipment, etc. according to customers' requirements, including special equipment in the industry, such as hydraulic rod cladding machine, pick cladding machine, valve cladding machine, etc.
PTA (Plasma Transferred Arc) uses a plasma arc to melt powder and the substrate surface, ideal for thicker layers (2-5mm) and high deposition rates. Laser Cladding uses a laser beam, offering much lower heat input, minimal distortion, and is better for high-precision repairs of thin-walled components.
Our machines ensure a true metallurgical bond between the coating and the base material. Unlike thermal spray coatings which are mechanically bonded, our cladding won't flake or peel under high stress or impact.
Yes. Our "Intelligent Robot Cladding Equipment" and "DH1440-B06 Automatic plasma surfacing robot" are designed for industrial-scale, continuous operation with integrated cooling systems and stable arc control.
We provide 24-hour consultation response and can support global projects with remote diagnostics and customized technical training for your local operators.
"In Oil & Gas, the Real Cost Is Downtime—Not the Component. When a choke valve fails, the traditional response was replacement. Now, with PTA hardfacing, we restore it to better-than-new condition."
"Achieving a high-quality overlay is not only about selecting the right alloy powder. One of the most critical factors that directly affects overlay performance is the dilution rate."
"In industries such as mining, screw conveyors are among the most frequent causes of unplanned production delay. Custom surfacing solves this problem permanently."
