In the current industrial landscape, procurement officers in the Oil & Gas, Mining, and Power Generation sectors are shifting from "low initial cost" to "Total Cost of Ownership (TCO)" models. PTA (Plasma Transferred Arc) welding has emerged as the gold standard for surface hardening because it offers a metallurgical bond that thermal spray cannot match, at a fraction of the cost of laser cladding for heavy-duty applications. Custom PTA solutions allow factories to extend component lifespan by up to 500%.
Shanghai Duomu, with over a decade of specialization, embodies the Experience, Expertise, Authoritativeness, and Trustworthiness required in high-stakes welding technology. As an independent R&D powerhouse, we don't just supply machines; we provide engineered outcomes. Our technical background ensures that every piece of equipment—from the DML-V03BD to robotic positioners—is built to withstand continuous 24/7 industrial operation.
Macro-economically, the drive toward Sustainability and Remanufacturing is fueling the demand for PTA technology. Instead of scrapping worn shafts or valves, global enterprises are utilizing our automated PTA and Laser cladding systems to restore dimensions with superior alloys. This reduces carbon footprints by minimizing the need for new raw material smelting and forging.
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 pride ourselves on bridging the gap between theoretical material science and practical industrial application.
Our commitment to excellence is reflected in our robust global supply chain, ensuring that every Custom PTA Weld Supplier partnership we form is backed by rapid response times and technical depth.

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 Touch →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.
Enhancing the durability of tillage tools and harvest components against soil abrasion.
High-precision cladding for engine components and high-temperature turbine blades.
Corrosion-resistant overlays for drill stabilizers, mud pump valves, and blowout preventers.
Hardfacing of rolls and continuous casting components to resist thermal fatigue and impact.
The next generation of PTA equipment will feature real-time melt pool monitoring using AI computer vision. This ensures zero-defect cladding by automatically adjusting amperage and powder feed rates mid-process.
Combining the high speed of Laser Cladding with the deep penetration and material flexibility of PTA. Our R&D is currently perfecting head designs that allow for simultaneous deposition.
Developing low-energy plasma torches and high-efficiency gas recycling systems to meet the stringent ESG (Environmental, Social, and Governance) requirements of the EU and North American markets.
"In Plasma Transferred Arc (PTA) hardfacing, achieving a high-quality overlay is not only about selecting the right alloy powder. The dilution rate is the most critical factor affecting performance..."
"Improving PTA hardfacing efficiency is not simply about increasing welding speed. Real industrial efficiency depends on deposition rates relative to energy consumption..."
"In Oil & Gas, the Real Cost Is Downtime—Not the Component. When a choke valve fails, the loss of production far outweighs the cost of a PTA-cladded replacement..."
Shanghai Duomu provides localized support for global clients, ensuring all machinery meets CE, ISO9001, and ASME standards. We understand that a factory in Germany has different safety requirements than a mining site in Australia. Our customization extends beyond the torch—we adapt the entire HMI (Human Machine Interface) and safety interlock systems to meet local regulations.
While Laser Cladding offers lower heat input, PTA provides a higher deposition rate and a stronger metallurgical bond for heavy layers. PTA is also significantly more cost-effective for large components in mining and steel manufacturing where high-wear resistance is needed over large surface areas.
Every machine undergoes a 48-hour continuous stress test before shipment. We provide a full metallurgical report of the cladding samples produced by your specific machine during the FAT (Factory Acceptance Test).
Yes. Our DML-V03CD and robotic positioners are designed with open communication protocols (Profinet/EthernetIP) to integrate seamlessly into Industry 4.0 factory environments.
Our systems are compatible with Cobalt-based (Stellite), Nickel-based, Iron-based, and Tungsten Carbide (Wc) reinforced powders. The high temperature of the plasma arc allows for the successful deposition of virtually any conductive alloy.
