Industry-leading hot wire TIG and plasma surfacing systems for high-integrity components.
Bridging the Gap Between Precision and Productivity in Modern Metallurgy.
Traditional Cold Wire TIG welding has long been the gold standard for quality, but it has historically struggled with low deposition rates. Hot Wire TIG (HWT) equipment revolutionizes this by using a dedicated power supply to preheat the filler wire via the Joule effect (I²R heating) before it enters the weld pool. This allows for deposition rates that rival MIG/MAG welding while maintaining the superior metallurgical integrity and slag-free results of the TIG process.
As noted in our field testimonials, achieving high-quality overlays in Plasma Transferred Arc (PTA) and HWT is deeply tied to the dilution rate. Our equipment is engineered to minimize base metal penetration, ensuring the cladding layer retains its specific properties—be it wear resistance or corrosion protection—from the very first layer. This is critical for applications in the oil and gas sector, such as mud pump valve seats.
The global manufacturing landscape is moving toward "Smart Welding." Our Hot Wire TIG systems are equipped with 6-axis robotic interfaces and real-time monitoring. By integrating AI-driven parameter control, we help manufacturers reduce human error and optimize gas consumption, aligning with modern ESG (Environmental, Social, and Governance) targets for sustainable manufacturing.
Leveraging Global Supply Chain Excellence and R&D Speed.
Unlike Western competitors, Shanghai Duomu leverages a condensed supply chain in the Yangtze River Delta, allowing us to go from client requirements to customized automated welding solutions in 40% less time.
Our facility adheres to ISO 9001 and CE certifications. We don't just "make" machines; we engineer reliability for aerospace military industry and nuclear power, where equipment failure is not an option.
Purchasing from a direct manufacturer eliminates middleman markups. Our "Affordable Plasma Transfer Arc Surfacing Torch" solutions provide premium performance at a price point that accelerates ROI for small and medium enterprises.

Our products have penetrated many strategic fields with mature technological means.
Shanghai Duomu has been a leading manufacturer and exporter of PTA cladding machine and Laser cladding machine for more than ten years. Our Independent R&D Team develops equipment that maintains efficient, long-term operation even in harsh environments like coal mines and metallurgy plants.
We effectively support large-scale remanufacturing projects with mature technological means, ensuring that components like screw conveyors in the cement industry can be salvaged rather than scrapped.
Understanding the shift in how enterprises source heavy-duty welding equipment.
Enterprises are moving away from replacing whole units. The trend is "Life Extension" through high-precision cladding. Our SWS1000 S-TIG machines are designed for on-site remanufacturing to minimize the cost of downtime.
For pressure vessels and nuclear power components, narrow-gap hot wire TIG is becoming mandatory. It reduces filler material usage by up to 60% while ensuring 100% X-ray quality pass rates.
The shortage of skilled TIG welders globally is driving the demand for robotic arm welding systems. Our 6-axis systems allow semi-skilled operators to produce master-level weld quality.
Case studies from the front lines of hardfacing and repair.
"In Oil & Gas, the Real Cost Is Downtime—Not the Component. When a choke valve fails due to sand erosion, traditional response is replacement. Our HWT solutions allow for mud pump valve seat recovery with zero loss in performance."
"Improving PTA hardfacing efficiency is not simply about increasing welding speed. Real efficiency depends on the precision of the deposit and the reduction of post-weld machining."
"Screw conveyors are often auxiliary, but they cause the most unplanned downtime in biomass energy. Our cladding technology extends their service life by 300%."
