In the realm of high-precision industrial manufacturing, Soudure Au Tig (Tungsten Inert Gas welding) has long been the gold standard for quality and aesthetic finish. However, as global industries transition toward Industry 4.0, the demand for higher deposition rates, lower dilution, and superior metallurgical bonding has led to the rise of Plasma Transferred Arc (PTA) and Laser Cladding technologies.
As a premier Custom Soudure Au Tig Supplier, Shanghai Duomu leverages over a decade of technical expertise to bridge the gap between traditional manual precision and automated industrial efficiency. We don't just provide machines; we provide Information Gain—deep insights into how surface engineering can extend the lifecycle of critical components by up to 300%.
Shift from manual TIG to robotic plasma cladding to reduce human error and increase consistency in aerospace and nuclear sectors.
Remanufacturing of worn components using laser cladding is saving global enterprises billions in raw material costs annually.
Development of high-entropy alloy powders specifically for PTA systems to combat extreme erosion and high-temperature corrosion.
The global industrial landscape is witnessing a seismic shift. Procurement teams in Europe and North America are no longer just looking for "suppliers"; they are seeking strategic partners who understand the nuances of the Heat Affected Zone (HAZ) and the critical nature of dilution rates. In Plasma Transferred Arc (PTA) hardfacing, achieving a high-quality overlay is not only about selecting the right alloy powder or optimizing welding parameters. One of the most critical factors that directly affects overlay performance is the dilution rate.
Shanghai Duomu represents the pinnacle of China’s Factory 4.0 initiative. Our manufacturing processes are defined by Supply Chain Resilience and Agile Production. Unlike traditional factories, we integrate an independent R&D team that develops, produces, and sells plasma cladding machine equipment in-house.
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.
Hardfacing of soil-engaging tools for 5x longer wear life.
Precision cladding of turbine blades and structural components.
Erosion-resistant coatings for drill stabilizers and valves.
Refurbishing of continuous casting rollers and forge dies.
I 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.
For industrial equipment operating in abrasive, erosive, corrosive, or high-temperature environments, wear is inevitable. The real challenge is not preventing wear altogether but choosing the most cost-effective maintenance strategy once wear occurs. Many maintenance teams are now turning to our customized plasma powder surfacing machines to restore parts to better-than-new condition.
"In Oil & Gas, the Real Cost Is Downtime—Not the Component. When a choke valve fails due to sand erosion, our DQF-LC602 automated welding equipment ensures a rapid return to service."
"In industries such as mining and cement, screw conveyors are among the most frequent causes of unplanned production delays. Our PTA hardfacing reduces these risks by 70%."
"Improving PTA hardfacing efficiency is not simply about increasing welding speed. It's about optimizing the deposition rate while maintaining metallurgical integrity."
A: While "Soudure Au Tig" (TIG) uses a non-consumable tungsten electrode to create a weld, PTA (Plasma Transferred Arc) uses a constricted arc to melt both the base metal and a filler powder. PTA offers significantly lower dilution (5-10% vs 20% in TIG) and much higher deposition rates, making it superior for hardfacing large industrial components.
A: Yes. Our R&D team specializes in matching machine parameters to specific metallurgical needs, whether you are using Stellite, Inconel, or Tungsten Carbide blends. We provide the powder feeders and torches necessary for these high-performance materials.
A: Our "Factory 4.0" approach ensures digital traceability of every machine component, rigorous QC using automated testing platforms, and a resilient supply chain that minimizes delays. We offer 24-hour response times for technical inquiries, bridging the time-zone gap.
A: Not necessarily. Laser cladding offers the lowest heat input and highest precision, ideal for thin-walled parts or aerospace blades. However, PTA is more cost-effective for heavy-duty applications like mining screw conveyors or large hydraulic rods where thicker deposit layers are required.
