Industrial Grade Solutions for Modern Surface Coating
The global welding and cladding industry is undergoing a paradigm shift from traditional repair methods to advanced surface engineering. Soudure Plasma, or Plasma Transferred Arc (PTA) cladding, has emerged as a cornerstone technology for enhancing the lifecycle of critical industrial components. In today's economy, where "Remanufacturing" is valued as a $100 billion industry, PTA cladding offers a sustainable alternative to replacing expensive parts.
From the coal mines of Australia to the aerospace hubs in France, the demand for wear-resistant and corrosion-resistant coatings is skyrocketing. Manufacturers like Shanghai Duomu are at the forefront, providing high-precision integrated plasma powder welding systems that outperform traditional TIG or MIG processes in terms of dilution rates and metallurgical bonding.
Automation is no longer optional. Modern plasma cladding systems are now fully integrated with 6-axis robotic arms (like our DH1440-B06), allowing for complex geometry surfacing with 0.1mm precision.
PTA welding reduces material waste. By applying high-performance alloys (Stellite, Tungsten Carbide) only where needed, industries reduce their carbon footprint and raw material costs by up to 60%.
Real-time data logging of welding parameters (current, voltage, powder feed rate) ensures traceability—a critical requirement for Nuclear and Aerospace sectors.
Proven Performance Across the Most Demanding Environments
Hardfacing plowshares and harvesters with PTA increases lifespan by 3x in abrasive soil conditions.
Repairing turbine blades and engine components requires the low heat input and high bonding strength provided by our laser cladding machines.
Drilling tools and valve seats in the Oil & Gas industry face extreme erosion. Our PTA solutions provide the ultimate shield.
Continuous casting rollers and forging dies undergo thermal fatigue. Customized cladding restores their dimensional accuracy.
In Plasma Transferred Arc (PTA) hardfacing, achieving a high-quality overlay is not only about selecting the right alloy powder. One of the most critical factors is the Dilution Rate. Our R&D team has optimized the plasma torch geometry to ensure that the base metal melting is kept to a minimum (typically < 5%), preserving the pure properties of the expensive cladding alloy.
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.
"In the Oil & Gas, the Real Cost Is Downtime—Not the Component. When a choke valve fails, traditional response was replacement. Now, with Duomu's PTA, we repair in 48 hours."
"Achieving high-quality overlay is about optimized welding parameters. Duomu's machines provide the consistency we need for our screw conveyors in biomass energy."
PTA (Plasma Transferred Arc) is generally more cost-effective for thicker layers and larger areas, offering higher deposition rates. Laser Cladding provides lower heat input and is ideal for thin layers and ultra-high precision repairs on sensitive materials.
Yes. We specialize in custom equipment, such as hydraulic rod cladding machines, valve cladding systems, and double-cone injection molding machine barrel inner hole cladding machines (DSL-LC401).
High dilution means the base metal mixes too much with the alloy, weakening the protective properties. Our PTA torches are designed to keep dilution below 5%, ensuring maximum hardness and wear resistance.
Absolutely. We export globally and provide 24-hour response for inquiries. Our equipment is built for "efficient long-term operation" in any industrial environment.
