High-precision industrial hardware for demanding manufacturing environments.
In the contemporary industrial landscape, the demand for components capable of surviving extreme abrasive, corrosive, and thermal environments has never been higher. Plasma Transferred Arc Welding (PTAW), often referred to as PTA surfacing, has emerged as the definitive solution for high-quality metallurgical bonding. Unlike traditional welding, PTAW offers a highly concentrated heat source, providing unparalleled control over dilution rates and deposit thickness.
As a leading China PTAW supplier, Shanghai Duomu is at the forefront of this technological revolution. With over a decade of deep-seated R&D and manufacturing excellence, we provide not just machines, but holistic "Surface Life-Cycle Management" solutions that reduce operational downtime and maximize the ROI of industrial assets.

Bridging the gap between heavy industry challenges and precision engineering.
Critical for turbine blade repair and engine component hardfacing, ensuring safety in high-stress environments.
Protecting drill stabilizers, valve seats, and mud pump components against severe erosion and H2S corrosion.
Enhancing the service life of cutting picks, crusher rollers, and excavator teeth through automated PTAW surfacing.
Extending the lifespan of boiler tubes and steam turbine parts in nuclear and coal-fired power plants.
One of the most critical factors in Plasma Transferred Arc (PTA) hardfacing is the dilution rate. High dilution means the base metal mixes too much with the cladding alloy, degrading the properties of the wear-resistant layer. Shanghai Duomu’s PTA systems are engineered to maintain dilution levels as low as 5%, ensuring the integrity of expensive alloy powders like Stellite or Tungsten Carbide.
The transition from manual welding to Numerical Control (NC) and Intelligent Robotic Cladding represents the future of the industry. Our DNC2000 and robotic systems utilize real-time sensor feedback to adjust arc voltage and powder flow, ensuring a consistent metallurgical bond that manual processes simply cannot replicate.
The global industrial trend is shifting from "Replacement" to "Remanufacturing." PTAW technology is a pillar of this shift, allowing companies to restore worn parts to "better-than-new" condition at 30-50% of the cost of a new component. Our commitment to sustainability drives us to innovate more energy-efficient plasma sources and higher deposition rate systems.
Navigating global trade requires more than just good machinery. Shanghai Duomu ensures every unit meets international safety and quality standards, including CE certification and ISO 9001 compliance. We provide:
