In the modern manufacturing landscape, component longevity and surface integrity are paramount. "Limpeza de Ferrugem a Laser" (Laser Rust Cleaning / Laser Derusting) has evolved from a niche technology to a core industrial standard. As a professional, custom manufacturer and supplier, Shanghai Duomu integrates advanced laser technologies with Plasma Transferred Arc (PTA) cladding systems to offer high-precision, non-contact, and environmentally clean surface restoration.
Whether targeting oxidation layers on offshore drill rigs, processing turbine blades, or preparing complex gantry systems, our custom systems ensure zero substrate damage. Traditional methods like sandblasting or chemical pickling suffer from high operational costs, safety hazards, and environmental regulations. Our custom laser systems overcome these hurdles, maximizing efficiency and enabling Factory 4.0 automation.
Before applying hardfacing materials or laser cladding overlays, surfaces must be 100% free of oxides, corrosion, and organic contaminants. Micro-impurities left behind trigger high dilution rates, micro-cracks, and structural delamination. Our unified solutions address both prep (laser rust cleaning) and deposition (PTA/Laser cladding) to guarantee metallurgical bonding integrity.

"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 petrochemical and heavy energy sectors scale up, automated surface hardening becomes crucial."
"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. Hardfacing screw flights using Duomu automated equipment reduces wear rates significantly."
"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. Proper substrate cleaning and heat management are essential."
"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 return on assets."
"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. Selecting reliable surfacing machinery preserves valve seal life."
"Our automated powder surfacing machines (like the DML-V03CD and DML-V03BD series) are designed to satisfy custom operational demands. By incorporating advanced optical tracking and precise plasma arc control, we enable manufacturers to execute complex hardfacing tasks with high repeat accuracy."
