Engineered for extreme wear resistance, micro-alloy precision, and seamless integration into high-output manufacturing lines.
Plasma Transferred Arc (PTA) welding is a high-energy, thermal overlay process engineered to deposit wear-, corrosion-, and heat-resistant alloy powders onto base metal components. Unlike traditional Shielded Metal Arc Welding (SMAW) or Submerged Arc Welding (SAW), PTA utilizes a constrained tungsten arc passing through a converging nozzle, resulting in extreme energy density and focused thermal profiles.
For industrial operators serving the Grenville commercial region, equipment longevity is directly tied to operational profitability. The primary advantage of Shanghai Duomu's PTA technology lies in its ultra-low dilution rate (3% to 8%). Dilution occurs when the substrate metal melts and mixes into the deposited cladding layer. Higher dilution degrades the hardness and alloy concentration of tungsten carbides or cobalt-base alloys. PTA preserves the full metallurgical properties of specialized powders in a single pass.
| Welding / Cladding Process | Base Metal Dilution (%) | Deposition Efficiency (%) | Deposit Thickness (Single Pass) | Thermal Distortion Risk | Automation Capability |
|---|---|---|---|---|---|
| Shanghai Duomu PTA Welding | 3% - 8% | 90% - 96% | 1.0 mm - 6.0 mm | Very Low | Fully Automated / Robotic CNC |
| Laser Cladding | 1% - 5% | 85% - 90% | 0.2 mm - 2.0 mm | Ultra Low | Fully Automated |
| TIG Hardfacing (GTAW) | 15% - 25% | 60% - 75% | 1.5 mm - 3.5 mm | Moderate to High | Semi-Automated / Manual |
| Submerged Arc (SAW) | 25% - 40% | 85% - 90% | 3.0 mm - 10.0 mm | Extremely High | Automated Gantry |
| Thermal Spraying (HVOF) | 0% (Mechanical Bond) | 50% - 70% | 0.1 mm - 0.8 mm | None | Robotic Spray Cell |
Tailored plasma surfacing and automated cladding solutions built to meet the rigorous demands of local production facilities, heavy equipment repair shops, and precision engineering firms in Grenville.
Local rebuild centers in Grenville handle extensive hydraulic cylinder repairs, excavator teeth reinforcement, and chassis wearing parts. PTA welding provides a dense, impact-resistant overlay using nickel-chromium matrix alloy powders combined with spherical tungsten carbide.
Petrochemical processing facilities and water treatment networks across Grenville rely on high-pressure gate, globe, and ball valves. Our inner-bore PTA plasma torches (DNPT series) cladding valve sealing faces and internal cylindrical cavities with Stellite 6 to prevent cavitation erosion.
Soil processing machinery, timber mulching teeth, and trenching picks undergo high-stress abrasive friction. Automated pick cladding systems like the DJC-LC305 deliver repeatable 360-degree hardfacing, reducing downtime for Grenville field contractors by over 400%.
At present, the company's products have penetrated into many fields such as aerospace military industry, nuclear power, petrochemical industry, coal mines, metallurgy and forging, agriculture, water conservancy and electric power, etc.
