TIG (Tungsten Inert Gas) welding, or GTAW, is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. As a leading manufacturer, we redefine "Soldador Tig" by integrating it into automated cladding systems, offering unmatched precision for critical industrial repairs.
Unlike traditional manual welding, our custom solutions provide concentrated heat and superior control. This is essential for applications requiring low dilution rates and minimal heat-affected zones (HAZ), especially in the aerospace and nuclear sectors.
We don't just supply machines; we build solutions. From specialized TIG torches for deep-hole welding to integrated plasma powder systems, our equipment is designed to meet the rigorous demands of modern manufacturing.
Shanghai Duomu's technology serves as the backbone for heavy industrial maintenance and manufacturing globally. We address the "cost of downtime" by providing remanufacturing tools that extend component lifespans by up to 300%.
Hardfacing of soil-engaging tools using PTA and TIG technology to resist extreme abrasion.
High-precision repair of turbine blades and structural components where structural integrity is non-negotiable.
Combating sand erosion and corrosion in mud pump valves and drill stabilizers through advanced surface cladding.
With an independent R&D team, Shanghai Duomu has spent over a decade perfecting the synergy between Plasma Transferred Arc (PTA) and TIG welding technologies. Our mission is to provide Information Gain to our clients—helping them understand that the real efficiency of a cladding process lies not just in speed, but in low dilution rates and metallurgical bonding quality.
Industrial Experience
500+ ProjectsCompleted Globally
As global industries shift toward sustainability, "remanufacturing" has become a multi-billion dollar sector. TIG and Plasma cladding allow companies to restore worn parts instead of scrapping them, reducing carbon footprints by up to 60% compared to new part manufacturing.
The shortage of skilled manual welders ("Soldador Tig") is driving the demand for automated systems. Our CNC-controlled and robotic welding cells ensure consistent quality that manual processes simply cannot match in high-volume production.
The development of new superalloys and metal matrix composites (MMCs) requires advanced welding heat control. Our equipment is optimized for Cobalt-based, Nickel-based, and Iron-based alloy powders.
Valve Seat Hardfacing: Using the DML-V03CD to apply Stellite 6 overlays for high-temperature steam valves.
Blade Repair: Precision laser cladding for gas turbine blades to restore aerodynamic profiles with zero distortion.
Ball Valve Automation: Automated DQF-LC602 systems for the chemical industry, ensuring leak-proof sealing surfaces.
Surface Hardening: Enhancing the wear resistance of gears and shafts through localized robotic laser hardening.
Our equipment adheres to international CE standards and ISO 9001:2015 quality management systems. We provide full documentation for welding procedure specifications (WPS) and procedure qualification records (PQR).
Based in Shanghai, we offer 24-hour technical response. Our engineers provide remote diagnostics and on-site training to ensure your team masters the "Soldador Tig" and PTA systems quickly.
We maintain a comprehensive inventory of tungsten electrodes, plasma nozzles, and powder feeders to ensure zero production downtime for our global partners.
Q: What is the main difference between TIG welding and PTA cladding?
A: While both use a tungsten electrode, TIG (Soldador Tig) typically uses a wire feed or manual rod, whereas PTA (Plasma Transferred Arc) uses metal powder. PTA offers higher energy density and much lower dilution, making it superior for hardfacing large industrial components.
Q: Can your machines be integrated with existing robotic arms?
A: Yes, our equipment is designed with open interfaces (PLC) to integrate seamlessly with FANUC, ABB, KUKA, and other industrial robotic platforms for fully automated cladding cells.
Q: What materials can be welded using your SWS1000 S-TIG machine?
A: The S-TIG system is exceptionally versatile, capable of welding stainless steel, carbon steel, nickel alloys, and titanium with high-speed precision and deep penetration.
Q: Do you provide training for operators?
A: Absolutely. We provide comprehensive training modules covering machine setup, parameter optimization for different powders, and routine maintenance protocols.
"Achieving a high-quality overlay in PTA hardfacing is not only about selecting the right alloy powder but optimizing the dilution rate. Shanghai Duomu's machines gave us the control we needed."
"In Oil & Gas, the real cost is downtime. Their valve cladding equipment reduced our lead times for repairs by 40%."
"For screw conveyors in mining, wear is inevitable. Their automatic plasma cladding solutions changed our maintenance strategy from reactive to proactive."
