In the modern industrial landscape, the longevity and reliability of mechanical components are paramount. As a leading Power Arc Welding Machine Manufacturer, Shanghai Duomu integrates over a decade of technical expertise into the design of Plasma Transferred Arc (PTA) and Laser Cladding systems. Unlike traditional welding, our "Information Gain" approach focuses on the dilution rate and metallurgical bonding—critical factors that define the success of industrial remanufacturing.
Our PTA machines utilize a high-density plasma arc to melt both the substrate surface and a filler material (usually powder). The result is a high-strength coating with extremely low dilution (typically <5%), ensuring the properties of the alloy powder are fully utilized.
The transition from mechanical bonding to metallurgical bonding is where we excel. By optimizing the heat-affected zone (HAZ), we prevent substrate distortion while achieving a bond that can withstand extreme abrasive and corrosive environments.
Integration with CNC and robotic arms allows for repeatable, high-precision cladding on complex geometries such as screw flights, valve seats, and hydraulic rods.
The global supply chain for welding technology has shifted toward China, driven by rapid R&D cycles and integrated manufacturing ecosystems.
China's manufacturing scale allows us to offer high-end PTA and Laser Cladding equipment at a fraction of the cost of European or North American competitors without compromising on component quality (using world-class IGPT modules and CNC controllers).
Located in Shanghai's industrial hub, we have immediate access to specialized alloy powder suppliers and electronic component manufacturers, enabling us to reduce lead times for custom equipment by 30-40%.
We don't just sell "off-the-shelf." Our technical department offers complete industrial solutions, from specialized torches for inner-hole cladding to massive gantry-style laser systems for aerospace components.
Our products have penetrated into many fields such as aerospace military industry, nuclear power, petrochemical industry, and more.
In industries like Oil & Gas, the real cost isn't the component—it's the downtime. When a choke valve fails, the financial loss per hour is staggering. Modern Power Arc Welding Machines are no longer just repair tools; they are the heart of "Remanufacturing."

PTA uses a plasma arc and is generally more cost-effective for thicker layers and larger areas, offering high deposition rates. Laser cladding uses a laser beam, resulting in a smaller heat-affected zone and higher precision for delicate components.
Yes, our DH1440-B06 robots and CNC controllers are designed for seamless integration into existing automated production lines using industry-standard protocols.
We analyze the client's material requirements and geometry. For example, our valve-specific machines are designed for the circular paths required for valve seats, while hydraulic rod machines focus on longitudinal stability.
Our machines support a wide range of powders, including Cobalt-based, Nickel-based, and Iron-based alloys, as well as Tungsten Carbide composites for extreme wear resistance.
