Bridging the gap between manual welding constraints and automated high-energy surface engineering.
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 dedication to research and development has enabled us to design and engineer systems that transition classic welding physics into next-generation digital metallurgical platforms.
We provide our global clients with comprehensive technical consultation, custom automation systems, and high-performance consumables to solve the most difficult abrasive wear, mechanical fatigue, and chemical corrosion challenges in harsh industrial environments.
Where precision meets high wear protection. Our cladding systems are active in major global industrial sectors.
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 engineers constantly iterate on TIG and MIG technologies to create hybrid solutions that meet challenging international manufacturing requirements.
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.
Meeting rising standards in heavy industry and automated manufacturing ecosystems worldwide.
Operating in international industrial markets requires adherence to regional certifications, electrical codes, and quality standards. Shanghai Duomu designs and manufactures equipment compliant with **ASME Section IX** (Welding and Brazing Qualifications), **ISO 3834** (Quality requirements for fusion welding of metallic materials), and **CE Directives** for electromagnetic compatibility and machinery safety.
In South Korea, where precision shipping yards, automotive factories, and semiconductor lines require high-quality welding processes, we provide local technical support. We assist engineering teams in evaluating the **Tig Mig 용접 차이** (welding difference) for specialized applications, helping them choose appropriate automation and PTA/Laser cladding upgrades to maximize productivity.
Real results from engineers implementing advanced surface modifications worldwide.
The PTA Welding Valve Application Guide is not just a process choice for valve manufacturers facing high wear, high corrosion, and high-temperature erosion working conditions, but also a key path to improving product competitiveness. As industries such as petrochemical, power generation, and marine engineering continue to demand longer valve lifespans, we chose Duomu's automatic plasma 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. Implementing Duomu's screw automatic welding system solved this pain point for our conveyor screws.
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 require a corrosion resistant cladding or abrasive resistance, keeping dilution under 5% is vital, which Duomu delivered.
In industries such as Oil & Gas, Mining, Power Generation, Cement, and Heavy Equipment Manufacturing, hardfacing is no longer just a repair process. It has become a critical technology directly related to equipment lifespan, downtime costs, maintenance frequency, and overall productivity. The 6-axis robotic arm system provides precise control over complex geometries.
In industries such as oil & gas, petrochemical, power generation, mining, and marine engineering, industrial valves are constantly exposed to severe operating conditions including high pressure, extreme temperatures, corrosive media, abrasive wear, and sand erosion. Duomu automated PTA cladding machines have significantly improved our valves' life span and seal reliability.
