Explore our high-performance automated systems engineered for heavy-duty surfacing, cladding, and metallurgical bonding.
In the lexicon of heavy-duty industrial surfacing and repair, Saldatura Arco Pulsato (Pulsed Arc Welding) plays a crucial role in controlling heat input, refining microstructure grain, and drastically reducing the dilution rate. Shanghai Duomu has spent over a decade integrating pulsed control systems into our state-of-the-art Plasma Transferred Arc (PTA) cladding and laser surfacing machinery.
By switching current rapidly between a high peak level (for robust material melting and metallurgical bonding) and a low background level (to cool the puddle and prevent base-metal distortion), our systems achieve high-precision deposition. This technology is critical for critical sectors including oil and gas, valve cladding, and mining where thermal management determines the ultimate mechanical integrity of the overlay.
Our dedicated technical department features independent R&D teams who develop, produce, and sell integrated plasma and laser cladding platforms. The result is a stable, highly efficient product lineup capable of continuous operation in severe industrial environments.
From advanced component sourcing to custom multi-axis integration, our Shanghai factory delivers premium performance with optimized capital costs.
Unlike standard machinery brokers, our factory constructs tailored configurations—including CNC-controlled welding positions, 6-axis robotic arms, and deep-bore welding torches designed for unique industrial geometry.
Based in the manufacturing powerhouse of Shanghai, we source high-grade optical paths, robust CNC assemblies, and custom tungsten electrodes efficiently, translating to lower lead times and higher equipment uptime.
Shanghai Duomu has designed, manufactured, and shipped PTA cladding systems and laser hardening machinery globally. We guarantee compliance with international electrical standards, ensuring seamless factory floor integration.
Our hardfacing, cladding, and pulsed arc welding solutions serve as the primary defensive barrier against erosion, abrasion, and high-temperature stress across crucial industrial sectors.
Enabling subsoiler tines, plowshares, and seed drills to withstand severe geological abrasive wear through tungsten carbide PTA cladding.
Laser cladding for turbine blades, critical engine mounts, and heat shields using nickel-chromium superalloys to maintain performance at extreme temperatures.
Protecting stabilizer wings, drill collars, and offshore mud pump pistons against heavy hydrogen-sulfide corrosive pitting and frictional wear.
Extending the lifespan of continuous casting rolls, forging dies, and hot shear blades through cobalt-base stellite alloy layering.
For global heavy industries, equipment wear is not merely a maintenance issue; it represents significant operational risk. In industries such as cement manufacturing, mining, power generation, and chemical processing, critical components like screw conveyors and hydraulic rods are highly vulnerable to catastrophic failure.
Shanghai Duomu offers end-to-end industrial solutions. By utilizing our proprietary automated laser and PTA cladding platforms, we allow companies to reclaim worn parts instead of buying new, reducing carbon footprints and capital expenses.
Our specialized systems feature automatic height detection, adaptive optical focus, and closed-loop temperature control to maintain consistent layer quality. This ensures minimal dilution of the base material while optimizing surface hardness.
Expert evaluations of how modern PTA surfacing and laser hardening technologies address wear mitigation and extend component lifespans.
"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 subsea drilling require ever-higher pressure limits, automated PTA hardfacing stands as the baseline process for stellite alloy application."
"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 shutdowns. Applying a tungsten carbide overlay via PTA welding dramatically mitigates abrasive wear."
"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. Keeping the dilution rate under 5% ensures maximum wear and corrosion resistance without losing alloy properties."
