Explore our industrial line of cladding, cleaning, and surface restoration solutions designed to eliminate operational down-time.
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 advanced surface optimization has positioned us as a top-tier supplier globally, facilitating robust cleaning, hardening, and restoration mechanisms across major industrial chains.
The Evolution of Modern Decarbonization via High-Efficiency Laser Rust and Oxidation Elimination Processes.
In heavy industrial environments, surface contamination—ranging from dense iron oxide (ferrugem) to chemical residue—represents the primary catalyst for component wear, weld failure, and structure compromise. The term "laser para limpar ferrugem" (laser to clean rust) defines a modern class of high-intensity, localized material cleaning systems that replace chemical baths, hazardous solvent treatments, and abrasive blast media. By incorporating pulsed fiber laser systems, industrial operators can selectively vaporize contamination layers without subjecting underlying substrates to thermal stress or structural deformation.
From an ecological standpoint, laser rust cleaning operates entirely dry and emission-free. The chemical waste streams generated by traditional pickling processes are eliminated, satisfying strict global ESG (Environmental, Social, and Governance) targets. When integrating rust cleaning with subsequent surface hardening or PTA cladding, the substrate's cleanliness level directly governs the quality of the metallurgical bond. Our systems deliver surface preparations that score a class SA 3 on Swedish Rust Standards, ensuring absolute adhesion levels for automated laser cladding.
The global demand for laser cleaning systems has accelerated, particularly within South American markets (e.g., Brazil), European manufacturing hubs, and Asian infrastructure zones. Industrial operations in Brazil require ruggedized equipment to combat the intense humidity that accelerates rust on agricultural machinery, maritime vessels, and mining transport belts. A high-efficiency laser rust cleaning supplier must offer multi-mode systems that handle varying depths of localized corrosion. Our machinery supports long-term operational resilience, lowering mechanical downtime and cutting asset reclamation costs by up to 60% compared to traditional grinding or replacement methods.
Our machinery adheres to international safety standards, including Class 4 laser safety integrations, CE certifications, and localized industrial safety norms (such as Brazil's NR-12 guidelines).
Our localized support network ensures prompt installation, rapid deployment of replacement nozzles, optics cleaning training, and fiber source diagnostics.
Designed to operate in dust-heavy, high-temperature, and corrosive chemical environments typical of metallurgical refineries and mining deposits.
Across diverse sectors, Shanghai Duomu products bridge the gap between initial surface cleaning and structural cladding reinforcement:

"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 down-time."
"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, maintenance frequency, and structural reliability."
"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, and abrasive sand erosion."

Fiber laser cleaning (Laser para limpar ferrugem) offers a dry, non-contact process that eliminates the storage, usage, and disposal costs of hazardous chemical solvents. It prevents hydrogen embrittlement in high-strength steels and allows for selective, micro-precise cleaning of specific areas without modifying the geometry of the bulk substrate.
The dilution rate refers to the percentage of substrate material that melts and mixes into the deposited hardfacing layer. A lower dilution rate (ideally under 5% to 10% in PTA) preserves the chemical integrity and hardness of the hardfacing alloy powder, providing maximum wear and corrosion resistance directly at the interface.
Yes. By coupling our laser cleaning heads with multi-axis industrial robots, operators can automate oxide removal pathways. This configuration is widely implemented before automated laser cladding or welding to achieve consistent, oxide-free surface preps.
Industrial installations require protective enclosures, proper exhaust ventilation to extract vaporized dust particulates, interlocked safety gates, and specialized eye protection (laser safety goggles) tuned to the wavelength of the fiber laser source.
Our technological integrations support heavy-duty industries across the globe.
