The PAW (Plasma Arc Welding) and PTA (Plasma Transferred Arc) processes are no longer just welding techniques; they are the bedrock of modern remanufacturing and surface fortification.
Unlike traditional MIG/TIG, the PAW process utilizes a constricted arc, offering energy density that rivals laser beams but at a fraction of the operating cost. This makes it ideal for thick-plate welding and heavy-duty surfacing.
Global industrial trends are shifting toward "Value Retention." Our custom PAW processes allow for the reclamation of high-value components in mining and aerospace, extending service life by up to 300%.
Our systems are designed for robotic synergy. With real-time data feedback and automated powder feeding, we provide a "Smart Factory" ready solution for suppliers worldwide.
Experience and Expertise (E-E-A-T): With over a decade of R&D at Shanghai Duomu, we have decoded the complex relationship between arc voltage, gas flow rates, and dilution levels. In Custom PAW Processes, the ability to maintain a stable "Keyhole" mode is critical for full-penetration welds without edge undercut.
The roadmap for PAW technology involves Hybrid Plasma-Laser systems, where the plasma arc provides the bulk thermal input while the laser stabilizes the weld pool and refines the microstructure. We are currently testing AI-driven melt-pool monitoring systems that can adjust parameters in milliseconds to prevent porosity.
Suppliers in North America and Europe are increasingly moving toward PTA (Plasma Transferred Arc) for cobalt and nickel-based alloy cladding. As a leading supplier, we ensure our machines meet global compliance standards including CE and ISO 9001:2015, providing Local Support through our global distributor network.
Where Precision Meets Durability
Enhancing wear resistance of plowshares and harvesters using PTA hardfacing.
Critical component repair using low-distortion laser cladding technology.
Surface protection for drill bits and valves against corrosive crude oil environments.
Remanufacturing of continuous casting rollers for steel production lines.
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. We specialize in providing complete sets of industrial equipment solutions.
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. Laser cladding equipment sold supports large-scale remanufacturing projects.
We provide automatic laser cladding equipment, intelligent robot cladding equipment, and special industry equipment like hydraulic rod cladding machines, pick cladding machines, and valve cladding machines.
PAW (Plasma Arc Welding) uses a constricted arc through a copper nozzle, resulting in higher energy density and a more stable arc compared to the unconstricted arc of TIG.
By applying a high-performance alloy layer (like Stellite or Tungsten Carbide) only where needed, you can use cheaper base metals for the rest of the component.
Yes, as a global supplier, we provide remote diagnostics and onsite commissioning through our authorized technical partners in key industrial hubs.
