In the competitive landscape of modern manufacturing, TIG Hot Wire (Tungsten Inert Gas Hot Wire) welding stands as a cornerstone of high-efficiency surface engineering. Traditionally, TIG welding was prized for its precision but criticized for low deposition rates. The "Hot Wire" evolution has fundamentally solved this bottleneck.
By pre-heating the filler wire through an independent power source before it enters the weld pool, manufacturers can achieve deposition rates comparable to MIG/MAG welding while maintaining the metallurgical purity and arc stability of TIG. This process minimizes the thermal input to the base material, significantly reducing the "Dilution Rate"—a critical KPI for high-end hardfacing applications in the aerospace and nuclear industries.
Shanghai Duomu, as a leading TIG Hot Wire manufacturer, has pioneered the integration of AI-driven control systems into these machines, ensuring that the wire temperature remains consistent even as welding speeds vary. This "Information Gain" in process control allows for 24/7 automated operation with zero defects.
Increase in Deposition Efficiency compared to Cold Wire TIG
Extremely Low Dilution Rates for Superior Surface Hardness
Located in the industrial hub of Shanghai, we leverage a robust ecosystem of metallurgical and electronic components, allowing for rapid prototyping and custom machine builds that outperform Western counterparts in lead time.
Our independent R&D team doesn't just assemble machines; we design the core plasma torches and power controllers. This deep technical background ensures that we can provide "Macro Industry Solutions" tailored to specific alloy powders.
With over ten years of export experience to over 50 countries, Shanghai Duomu products are built to international standards (CE/ISO), ensuring reliability in the most demanding environments like coal mines and nuclear plants.
Penetrating critical sectors with specialized cladding solutions
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.
The integration of TIG Hot Wire and Laser Cladding on a single robotic platform. This allows for rapid volume build-up with TIG and precision finishing/thin layering with Laser, optimizing cost-per-kg of deposited metal.
Modern suppliers are moving towards IoT-enabled machines. Shanghai Duomu’s newest systems offer real-time data logging, allowing global enterprises to monitor cladding quality from their headquarters, ensuring 100% compliance.
Remanufacturing vs. Replacement. By using PTA or TIG Hot Wire to repair worn shafts or blades, companies reduce their carbon footprint by 80% compared to manufacturing new parts. This is a key driver for global procurement requirements.
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. 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.
Get Technical SupportThe primary advantage is deposition speed. Hot wire TIG can deposit up to 4kg/hour, whereas cold wire is often limited to 1kg/hour. Additionally, the pre-heated wire melts more easily, requiring less arc energy and thus causing less heat distortion in the base part.
Yes. Our PTA and Laser Cladding systems are specifically designed for high-performance alloys. We provide customized parameters for cobalt-based (Stellite), nickel-based (Inconel), and tungsten carbide powders to ensure maximum wear resistance.
Shanghai Duomu offers comprehensive remote and on-site training. For global enterprises, we provide detailed technical documentation and video support, ensuring your operators can master the equipment within 24 hours.
