In the modern industrial landscape, "Custom TIG Welding" and "Plasma Transferred Arc (PTA)" have transitioned from simple joining techniques to comprehensive surface engineering solutions. Shanghai Duomu provides specialized equipment designed to counteract extreme wear, corrosion, and high-temperature oxidation in critical environments.
Our solutions target the 'Total Cost of Ownership'. By applying metallurgical overlays of tungsten carbide, stellite, and other super-alloys, we extend the service life of components by 300% to 500%, significantly reducing unplanned downtime in heavy industries like mining and forging.
Integration of 6-axis robotic arms with high-precision TIG/PTA torches allows for complex geometry welding. This shifts the focus from manual labor dependency to high-output, repeatable digital manufacturing, satisfying the demands of Industry 4.0.
At present, our products have penetrated into many critical fields such as aerospace military industry, nuclear power, petrochemical industry, coal mines, metallurgy and forging, agriculture, water conservancy, and electric power.
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. Our R&D center is at the forefront of plasma power source development, ensuring that our TIG and PTA systems maintain superior arc stability.
We provide customized equipment, automatic laser cladding equipment, automatic plasma cladding equipment, and intelligent robot cladding equipment including special equipment for hydraulic rod cladding, pick cladding, and valve seat surfacing.
Our independent R&D team develops, produces, and sells plasma cladding machine equipment. The welding machines feature stable performance for efficient long-term operation. Laser cladding equipment effectively supports large-scale remanufacturing projects with mature technological means.
From DML-V03CD plasma powder surfacing to DQF-LC602 ball valve automated systems, our engineering team modifies parameters to meet specific material dilution and metallurgical bonding requirements.
With an ISO-certified manufacturing process, we ensure every "China Plasma Torch 500A" and "High Integration Plasma Welder" meets rigorous international standards for safety and performance.
Operating across 40+ countries, we understand the logistical complexities of shipping heavy industrial machinery. Our equipment is packed for maritime safety and includes all necessary customs documentation for seamless importation.
All our custom TIG welding systems and PTA machines comply with CE, RoHS, and local electrical standards. We provide comprehensive documentation to ensure your workshop meets safety audits during the integration of robotic systems.
We offer remote diagnostics and local technician dispatch for critical maintenance. Our commitment is to be in touch within 24 hours for any inquiry, ensuring your production line never stops due to equipment failure.
In Plasma Transferred Arc (PTA) hardfacing, achieving a high-quality overlay is about minimizing the dilution rate. High dilution compromises the properties of the expensive alloy powder. Our DML series optimizes arc pressure to maintain dilution below 5%.
In Oil & Gas, the real cost is downtime, not the component. A mud pump valve seat failure costs thousands in lost production per hour. Our cladding systems pay for themselves by doubling the MTBF (Mean Time Between Failures) of these parts.
Our integrated plasma powder welding machines (DML-V03BD) feature synchronized powder feeding systems that ensure consistent metallurgical bonding even on complex vertical or overhead orientations.
The welding industry is evolving towards "Zero-Defect Manufacturing." Shanghai Duomu's roadmap focuses on three pillars:
Real-time monitoring of arc characteristics to adjust parameters instantly, compensating for material variations during the welding process.
Developing high-efficiency laser hardening processes that reduce energy consumption by 40% compared to traditional induction heating.
Merging PTA and Laser technologies into a single workstation to provide both high deposition rates and precision fine-cladding capabilities.
Cloud-based monitoring of equipment health and production data, enabling managers to oversee multiple factories from a central dashboard.
While both use a non-consumable tungsten electrode, PTA (Plasma Transferred Arc) uses a constricted arc and a powder feed system. This allows for higher energy density, lower dilution, and the ability to use specialized powders like Stellite or Tungsten Carbide that cannot be used in traditional TIG wires.
Yes. Our "6 Axis Robot Arm Welding Machine" and "Manipulator Positioner" systems are designed with universal communication protocols. We provide the control interface to sync our power sources with all major robotic brands.
We provide comprehensive video training and detailed technical manuals. For critical failures, we offer "AR-assisted remote maintenance" where our engineers guide your local team through the repair process in real-time.
Laser cladding is ideal for stainless steels, nickel-based alloys, and cobalt-based alloys on substrates where heat-affected zones (HAZ) must be minimized to prevent distortion of high-precision parts.
