In the modern industrial landscape, "Custom Spwanie Tig" (referring to high-end precision TIG and Plasma-integrated welding) has transcended basic joining techniques to become a cornerstone of Surface Engineering. As a leading manufacturer, Shanghai Duomu has observed a shift from reactive maintenance to proactive "Life Cycle Extension" strategies across global enterprises.
Advanced Plasma Transferred Arc (PTA) cladding and Laser Cladding are no longer optionalโthey are essential for industries facing extreme abrasion, corrosion, and thermal fatigue. Our factory focuses on minimizing the Dilution Rate while maximizing Metallurgical Bonding, providing a technical advantage that traditional welding cannot match.

Efficiency Gain
Shanghai Duomu's products have penetrated high-stakes fields including aerospace military industry, nuclear power, petrochemical industry, and more.
Providing precision repair for turbine blades and engine components where metallurgical integrity is non-negotiable. Our laser hardening robots ensure micro-structural stability.
Surface hardfacing for drill bits, stabilizers, and valves. In Oil & Gas, the real cost is downtime; our PTA systems extend component life by up to 400%.
Heavy-duty cladding for rollers and forging dies. Our automated systems like the DNC2000 handle large-scale planar surfacing with consistent quality.
Hardfacing for soil-engaging tools. Custom Spwanie Tig technology allows for the application of Tungsten Carbide layers to withstand high-impact abrasion.
Shanghai Duomu houses an independent R&D team focused on the convergence of AI and Plasma technology. Our technical roadmap includes:
We provide customized equipment including hydraulic rod cladding machines, valve cladding machines, and screw brick machine systems.
As a global supplier based in Shanghai, we understand that localized support and compliance are vital. Our machines are built to international standards (CE, ISO) ensuring they meet the rigorous safety and quality demands of European and North American markets.
We provide 24-hour technical response times and comprehensive on-site training for global enterprises. Whether you are remanufacturing a screw conveyor in a cement plant or cladding a valve seat in an offshore rig, our expertise ensures your operation never stops.
"In PTA hardfacing, the dilution rate is everything. Shanghai Duomu's equipment allows us to maintain a low dilution rate, which directly impacts our overlay performance in abrasive environments."
"In Oil & Gas, the Real Cost Is DowntimeโNot the Component. Their repair welding machines have saved our mud pump valve seats from premature failure, drastically reducing Opex."
"Screw conveyors are often auxiliary but cause massive unplanned shutdowns. Hardfacing with Duomu's PTA systems has changed our maintenance strategy from replacement to restoration."
PTA (Plasma Transferred Arc) is generally more cost-effective for large-scale heavy-duty surfacing and high-deposition rates. Laser Cladding offers a smaller heat-affected zone (HAZ) and higher precision, ideal for delicate components like turbine blades.
We use high-grade internal components and a proprietary cooling system. Our machines, such as the DML-V03AD, are designed for 24/7 industrial cycles with minimal maintenance requirements.
Yes. Our R&D team specializes in optimizing welding parameters for Cobalt-based, Nickel-based, and Iron-based alloy powders to meet specific hardness and corrosion resistance requirements.
We provide comprehensive digital support, spare parts kits with every machine, and on-site engineering support through our global partner network. We respond to inquiries within 24 hours.
