In the era of Industry 4.0, the demand for Plasma Transferred Arc (PTA) Welding Machines has transitioned from simple repair tools to core components of advanced manufacturing lines. Global enterprises in the aerospace, mining, and oil & gas sectors are increasingly prioritizing surface engineering to extend the lifecycle of high-value components.
The "Information Gain" Reality: Unlike traditional MIG/TIG welding, PTA technology offers a metallurgical bond with significantly lower dilution rates (3-10%). This means you achieve the desired alloy properties in a single layer, reducing powder consumption by up to 30% and cutting total production time by 40%.
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 commitment to E-E-A-T principles ensures that every piece of equipment we produce meets stringent international standards for reliability and precision.

We maintain an independent R&D team that 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.
Get in touchThe next generation of PTA machines will feature real-time melt pool monitoring using AI vision. This allows for autonomous parameter adjustment to ensure zero-defect cladding even on complex geometries.
Combining the high speed of Laser cladding with the deep penetration and metallurgical stability of PTA. Our DXB-NC301 and DYY-LC501 series are already leading this hybrid transition.
Focused on "Circular Economy" solutions, our machines are designed for the remanufacturing of worn parts, reducing the need for new raw material extraction by up to 80%.
Our 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.
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.
What is Dilution? It is the percentage of the base metal that melts and mixes with the deposited alloy. In traditional welding, high dilution (20-30%) often "waters down" the hardfacing properties. Our PTA technology keeps this below 5%, ensuring that if you pay for high-grade Tungsten Carbide powder, you get the performance of high-grade Tungsten Carbide on the surface.
"In Oil & Gas, the Real Cost Is Downtime—Not the Component. When a choke valve fails, the traditional response was replacement. With Duomu's PTA, we repair in situ, saving millions."

"Improving PTA hardfacing efficiency is not simply about speed. The real efficiency lies in the consistency of the overlay. Shanghai Duomu delivers that consistency."
Production Director, Mining Equip
"For screw conveyors in biomass energy, wear is inevitable. PTA surfacing has increased our service life by 400%."
Plant Manager
A: While both provide high-quality overlays, PTA is generally more cost-effective for thicker coatings (above 2mm) and has a better deposition rate for large areas. Laser Cladding is superior for precision parts where the Heat Affected Zone (HAZ) must be kept to an absolute minimum.
A: Yes, our equipment is specifically optimized for Cobalt-based, Nickel-based, and Iron-based alloy powders, as well as Tungsten Carbide composites.
A: Absolutely. We provide complete technical documentation, CE certification, and onsite commissioning/training for our global clients.
