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 expertise lies in the integration of Gás De Soldadura De Plasma (Plasma Welding Gas) systems that deliver unmatched energy density for surface engineering.
We possess 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. Furthermore, our laser cladding equipment effectively supports large-scale remanufacturing projects.
Our mature technological means provide complete sets of industrial equipment solutions, ensuring that every China Gás De Soldadura De Plasma system meets international safety and performance standards.
Procurement departments in Fortune 500 companies now prioritize Information Gain and Sustainability. In the realm of plasma surfacing, this means selecting equipment that minimizes powder waste and maximizes the service life of expensive base materials.
Whether you are in the Oil & Gas sector looking for mud pump valve protection or Aerospace requiring turbine blade repair, our solutions are engineered for global compliance and localized operational ease.
At present, our 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.
Hardfacing of plowshares and harvesters to resist abrasive soil wear.
High-precision PTA surfacing for engine components and landing gears.
Corrosion-resistant cladding for drill bits and offshore valves.
Restoration of heavy-duty rolls and molds using automated plasma systems.
The industrial landscape is shifting toward Industry 4.0. Our technical roadmap for Gás De Soldadura De Plasma equipment is focused on three pillars:
In the global commercial arena, the demand for localized support and compliance is paramount. Shanghai Duomu ensures that all systems exported to Europe, the Americas, and Southeast Asia adhere to CE, ASME, and local environmental regulations regarding welding emissions.
"In Plasma Transferred Arc (PTA) hardfacing, achieving a high-quality overlay is not only about selecting the right alloy powder... One of the most critical factors is the dilution rate."
"In Oil & Gas, the Real Cost Is Downtime—Not the Component. When a choke valve fails, the traditional response is replacement, but PTA offers a better way."
"For screw conveyors in mining and cement, wear is the cause of unplanned downtime. Hardfacing extends life significantly."
The plasma gas (usually Argon) is ionized to create the plasma arc, while the shielding gas protects the weld pool from atmospheric contamination. The quality and flow control of these gases determine the stability of the arc and the final metallurgical properties of the cladding.
All our equipment is manufactured under ISO 9001 standards. We provide comprehensive documentation, including wiring diagrams and pressure vessel certifications where applicable, to ensure seamless integration into global production lines.
Yes. We specialize in customized equipment like hydraulic rod cladding machines, valve cladding systems, and intelligent robot integrations tailored to specific workpiece geometries.
Standard machines are typically available within 4-6 weeks, while complex robotic integrations may take 8-12 weeks depending on the technical requirements.
