Discover our highly advanced automated welding machines, custom plasma torches, and robust cladding equipment designed to minimize down-time and increase production lifetimes.
In high-performance industrial engineering, the term TIG Kaynağı (Tungsten Inert Gas Welding) represents the standard for control, cleanliness, and fusion precision. Yet, modern manufacturing demands have pushed traditional TIG processes past their physical boundaries. To fight severe erosion, corrosion, and extreme high-temperature oxidation, modern facilities rely on optimized fusion techniques including Plasma Transferred Arc (PTA) and Laser Cladding.
As global manufacturers seek customized setups, Shanghai Duomu bridges the gap by engineering multi-process arc solutions. From specialized heat-resistant tungsten electrodes to highly automated, CNC-controlled cladding systems, we customize each unit to match the exact metallurgical parameters required by your operational workflows.
Standard catalog welders often fail to satisfy the strict geometry tolerances of specialized tasks like deep-bore cladding, aerospace components, or mining screw repairs. Customized arc control allows for precise heat control, preventing burn-through, optimizing deposition rates, and protecting precious base materials from unwanted deformation.
Deciding between Custom TIG, Plasma Arc (PTA), and Laser Cladding based on critical metallurgical parameters.
| Feature / Parameter | Custom TIG Kaynağı (GTAW) | Plasma Transferred Arc (PTA) | Laser Cladding Surfacing |
|---|---|---|---|
| Heat Source | Electric Arc via Tungsten Electrode | Constrained High-Energy Plasma Arc | High-Power Focused Laser Beam |
| Dilution Rate | 10% - 15% (Typical) | 3% - 8% (Highly Controlled) | < 5% (Minimal) |
| Deposition Efficiency | 0.5 - 1.5 kg/h | 2.0 - 10.0 kg/h | 1.0 - 5.0 kg/h |
| Heat-Affected Zone (HAZ) | Wide (Relatively high thermal stress) | Medium (Concentrated energy path) | Very Narrow (Micro-scale thermal impact) |
| Consumable Format | Wire, Rods | Metal/Alloy Powders | Powders or Fine Wire Alloys |
| Ideal Applications | Thin sheets, structural joints, pipes | Valve seats, screw conveyors, mining picks | Turbine blades, hydraulic cylinder rods |
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.
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.
By integrating strict quality management with cutting-edge electronics, we have established ourselves as a reliable technology partner for heavy manufacturing and maintenance. We focus on enhancing component performance through customized hardfacing overlays that double—or even triple—the lifespan of worn metal components.
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.
Our proprietary arc-stabilizing feedback technology protects custom TIG operations and plasma surfacing programs from sudden changes in distance. This ensures smooth weld passes, even over uneven geometries.


















In today's challenging industrial market, maintaining supply chain resilience is vital. Operating our advanced production facilities in Shanghai allows us to benefit from the region's complete metallurgical manufacturing ecosystem. From raw tungsten refining to manufacturing complex CNC multi-axis positioners, we manage the entire value chain in-house.
This complete supply chain integration translates to direct advantages for our global clients:
Our heat-resistant tungsten electrodes and alloy powders are sourced directly from verified raw material producers, ensuring minimal trace impurities.
Every custom torch and nozzle is machined in-house on high-precision multi-axis CNC machines to maintain tight dimensional tolerances.
Each automated system undergoes a 48-hour continuous test cycle under load before shipping, minimizing setup adjustments upon delivery.
The welding industry is transitioning toward digital automation and integrated sensing. Shanghai Duomu is leading this shift by developing real-time monitoring systems that dynamically adjust parameters during operation.
We are actively integrating machine-vision monitoring with closed-loop controls into our PTA and Laser Cladding machines. By tracking heat distribution along the weld path in real-time, our software makes micro-adjustments to travel speed and powder feed rates, resulting in uniform, defect-free deposition.
Global industrial procurement demands reliable field support and compliance with regional safety rules. Our machinery is fully CE certified and aligns with standard international safety and manufacturing directives.
To support users in local markets, we offer structured technical assistance, including online video diagnostics, custom replacement parts delivery, and commissioning support from our regional field engineering partners.
We can provide customized equipment, automatic laser cladding equipment, automatic plasma cladding equipment, intelligent robot cladding equipment, etc. according to customers' requirements, including special equipment in the industry, such as hydraulic rod cladding machine, pick cladding machine, valve cladding machine, etc.
Technical expertise shared by field operators and production managers using Shanghai Duomu systems.
"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. Whether you need low dilution or robust surface integration, Shanghai Duomu's machines offer consistent, repeatable precision."
"Introduction Improving PTA hardfacing efficiency is not simply about increasing welding speed or depositing more alloy within a shorter time. In industrial production, the real efficiency of a Plasma Transferred Arc (PTA) hardfacing process depends on machine stability, consistent arc constraint, and the durability of the welding torch under high-temperature loads."
"In Oil & Gas, the Real Cost Is Downtime—Not the Component When a choke valve fails due to sand erosion, a mud pump valve seat wears beyond tolerance, or a drill stabilizer reaches the end of its service life, the traditional response of replacement is too expensive. Shanghai Duomu's automatic cladding machines have helped us rebuild components quickly and reliably."
"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 have switched from standard TIG repair to Duomu's automated plasma cladding systems."
"In industries such as mining, cement, power generation, steelmaking, chemical processing, and biomass energy, screw conveyors are often regarded as auxiliary equipment. However, maintenance data shows that they are among the most frequent causes of unplanned production downtime. Protecting them with PTA surfacing extends operational life significantly."
