Engineered to withstand severe abrasion, localized thermal stresses, and corrosion-heavy operations across complex environments.
Modern heavy-duty industries function under extreme tribological, thermomechanical, and electrochemical stresses. Standard structural alloys lack the specific properties to survive in these severe environments without premature degradation. This is where Laser Cladding and Plasma Transferred Arc Welding (PTAW) play a critical role, depositing custom metallurgically bonded coatings that dramatically extend the operational lifecycle of crucial capital equipment.
By utilizing highly concentrated heat sources (laser beams or plasma arcs), these technologies melt a target metal substrate and an alloyed powder precursor simultaneously. The resulting rapid solidification creates an exceptionally dense protective layer with minimal dilution rates, a narrow heat-affected zone (HAZ), and minimal thermal deformation. This structural optimization translates to reduced material waste, superior wear resistance, and minimized system 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.
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 facility integrates advanced power electronics design, precision multi-axis CNC movement systems, and real-time process monitoring technology. This allows us to serve tier-1 global aerospace, metallurgy, and petrochemical clients who mandate strict compliance with industry manufacturing standards.

Understanding the structural advantages, deposit rates, and heat inputs of Laser Cladding versus Plasma Transferred Arc Welding.
A highly focused, coherent laser beam serves as the energy vector, vaporizing and melting the surface target area with extreme precision. Powder feedstock is injected via coaxial or lateral nozzle systems.
Utilizes a constricted plasma arc between a non-consumable tungsten electrode and the workpiece. The powder material is gas-delivered directly into the plasma arc stream.
Insights into dilution factors, hardfacing practices, and field engineering challenges for valves, conveyors, and mining implements.
"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 mining continue to push parameters, optimizing dilution rates and using cobalt-based alloys on seating faces determines ultimate valve service lifespan."
"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. Laser Cladding these high-wear flight profiles with Chromium Carbide or Tungsten Carbide matrices keeps operational continuity at its peak."
"In Plasma Transferred Arc (PTAW) 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 parent metals from diluting critical elements ensures consistent hardness values through the entire clad layer, preventing premature friction failure."
"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 integrity under high loads. Investing in automated robotic integration keeps overlay profiles highly consistent and repeatability near perfect."
"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. Custom laser cladding deposits highly customized wear-resistant coatings (e.g. Stellite 6, Inconel 625) without modifying core component bulk mechanical behaviors."
"Working with Shanghai Duomu has allowed us to upgrade our global field service machinery. Their integrated PTA and laser cladding solutions handle the most demanding repair operations on hydraulic cylinders, mill shafts, and crushing rollers. Process stability and consistent weld overlays minimize final grinding steps, providing massive processing speed gains."
