TIG (Tungsten Inert Gas) welding, also known as Gas Tungsten Arc Welding (GTAW), is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. The weld area and electrode are protected from oxidation or other atmospheric contamination by an inert shielding gas (argon or helium).
In the context of China Factories, the term "TIG Kaynağı" has evolved from simple manual joining to high-precision automated cladding and surfacing. Shanghai Duomu, a leader for over ten years, integrates this fundamental physics into PTA (Plasma Transferred Arc) technology, which offers higher energy density and more stable arc control than traditional TIG.
The global welding equipment market is shifting toward automation and remanufacturing. With an annual growth rate exceeding 6%, industries are moving away from "discard and replace" models toward "repair and reinforce" strategies.
China has become the global hub for Intelligent Cladding, where TIG-based and Plasma-based systems are used to apply wear-resistant alloys to critical components in oil & gas, mining, and power generation sectors.
1. Robotic Integration: 6-axis robots are now standard for complex geometry cladding.
2. Hybrid Processes: Combining Laser and TIG/Plasma to optimize speed and heat input.
3. Data-Driven Welding: IoT-enabled machines like the ESD-9100 monitor parameters in real-time for zero-defect production.

The current state—Plasma Transferred Arc systems with digital powder feeders (like DML-V03CD) allowing for precise dilution control.
Integrating AI vision systems to automatically detect wear patterns and path-plan the cladding robot in 3D space.
PTA (Plasma Transferred Arc) offers a higher energy density and a more focused arc compared to TIG. This results in faster deposition rates, lower dilution with the base metal, and a much narrower heat-affected zone (HAZ), making it superior for industrial hardfacing.
Yes. Shanghai Duomu specializes in customized equipment, including hydraulic rod cladding machines, valve cladding systems, and intelligent robot cladding cells tailored to the specific geometry and material requirements of our clients.
In hardfacing, dilution rate is the percentage of the base metal that melts and mixes with the cladding alloy. A high dilution rate can "pollute" the alloy, reducing its hardness and wear resistance. Our systems are engineered to maintain a low dilution rate for maximum performance.
In industries like Oil & Gas, the real cost is downtime. Cladding a worn component costs significantly less than a new replacement and can often result in a part that lasts 2-3 times longer than the original due to superior alloy selection.
"In Plasma Transferred Arc (PTA) hardfacing, achieving a high-quality overlay is not only about selecting the right alloy powder. One of the most critical factors is the dilution rate..."
"Improving PTA hardfacing efficiency is not simply about increasing welding speed. The real efficiency depends on the stability of the industrial process..."
"In Oil & Gas, the Real Cost Is Downtime—Not the Component. When a choke valve fails, the traditional response is replacement, but cladding offers a faster solution."
