Browse our top precision-engineered plasma transferred arc (PTAW) torches, automatic cladding units, and advanced laser deposition machines tailored for multi-industry hardfacing.
As a premier Fournisseur Machine De Soudage Plasma based in Shanghai, China, Shanghai Duomu has engineered and exported high-caliber PTA (Plasma Transferred Arc) and Laser Cladding machines for over a decade. Our robust technological pedigree guarantees that global buyers bypass trading middlemen, securing direct-from-factory innovations.
China's manufacturing ecosystems deliver unmatched advantages for advanced surface cladding technology:
A key performance metric in hardfacing is the dilution rate. High dilution compromises the chemical properties of deposited powders (such as Stellite or Tungsten Carbides). Our PTA systems maintain dilution rates below 5%, ensuring maximum wear and thermal resistance from the first deposit layer.
Modern industrial operations demand smart integration. Our systems include intelligent robot cladding setups and custom manipulator positioners. We customize equipment configurations specifically for hydraulic rods, mine picks, agricultural shear blades, and heavy-duty petrochemical valves.
Laser cladding delivers minimal heat input, minimizing structural distortion in sensitive assemblies. Shanghai Duomu's laser machines provide precise, metallurgical bonding layers suitable for high-precision components, including turbine blades and high-pressure valves.
Shanghai Duomu supports an independent R&D team specialized in designing, producing, and supporting high-performance plasma cladding machinery. Our systems are engineered to run continuous shifts in demanding environments (such as coal mines, agricultural equipment fabrication, and petroleum refineries).
For global heavy industries, we supply full industrial cladding solutions: from metallurgical powder alloy suggestions (Cobalt-based, Nickel-based, or Carbide matrices) to optimal programming profiles for complex geometries.
Our machines are deployed across diverse, demanding industrial sectors, extending the lifespan of machinery operating under severe friction, impact, temperature, and corrosion.
From nuclear plant valve seats and petrochemical flow pipes to steel casting rollers, our PTA and Laser systems deposit precise, wear-resistant layers, increasing service life up to 300%.
When purchasing high-investment industrial machinery, meeting strict regulatory guidelines is non-negotiable. Shanghai Duomu systems are manufactured to conform to international standards:
Minimizing downtime is a primary objective for our global clients. We provide a dual-channel technical support network:
"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."
"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 delays."
"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."
"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, and maintenance frequency."
"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."
Our PTA setups maintain dilution rates below 5%, ensuring deposited alloys (such as Stellite or Tungsten Carbides) keep their original hardness properties in the first weld pass, reducing cost-per-square-inch significantly.
