Micro plasma welding (MPW) has transitioned from a niche aerospace technology to a cornerstone of Industry 4.0. As electronics and medical devices shrink, the demand for stable arcs at currents as low as 0.1A has skyrocketed worldwide.
Our R&D focuses on Digital Arc Control and AI-Integrated Monitoring. By reducing the heat-affected zone (HAZ), our systems ensure metallurgical integrity in sensitive alloys like Titanium and Inconel.
Adhering to ISO 9001 and CE standards, our factory ensures every unit passes rigorous stress tests. We provide full traceability for components used in nuclear and military sectors.
In the modern manufacturing landscape, "precision" is no longer just a metric—it is a competitive necessity. Micro Plasma Welding (MPAW) represents the pinnacle of arc welding technology, offering a concentrated, stable energy source that surpasses traditional TIG welding in consistency and control. As a leading manufacturer with over a decade of experience, we provide systems that enable factories to achieve welds on foils as thin as 0.05mm with zero distortion.
Our systems are engineered for diverse macro-industrial environments:
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.
Our products have penetrated into aerospace military industry, nuclear power, petrochemical industry, coal mines, metallurgy and forging, agriculture, water conservancy and electric power.
Unlike standard suppliers, we integrate Information Gain into our client consultations. We don't just sell a machine; we provide a deep metallurgical analysis of your specific application. Our Plasma Transferred Arc (PTA) systems offer a dilution rate control of less than 5%, ensuring that the hardfacing layer retains its maximum hardness and wear resistance from the very first millimeter.
Precision joining of fuel injectors and sensor housings in high-volume European and Asian automotive hubs.
On-site repair of drill stabilizers and valve components using our portable cladding units.
Enhancing the service life of picks and crushing equipment through automated surfacing.
Ultra-fine welding of battery tabs and connectors in consumer electronic assembly lines.
Micro Plasma provides a constricted arc via a copper nozzle, resulting in higher energy density and a more stable arc at low currents. This leads to less thermal distortion and a smaller heat-affected zone compared to TIG.
Yes, all our high-quality plasma and laser cladding systems are equipped with industrial communication protocols (RS485/Ethernet) for seamless integration with FANUC, ABB, and KUKA robotic arms.
We provide 24/7 remote diagnostic support, localized spare parts depots in key regions, and comprehensive training videos and manuals in multiple languages.
Through precise control of the pilot arc and main arc current, along with optimized powder feeding speed, our machines keep dilution under 5-10%, preserving the properties of the alloy powder.
"In Oil & Gas, the Real Cost Is Downtime—Not the Component. The PTA hardfacing solutions from Duomu reduced our maintenance cycles by 40%."
"The precision of their micro plasma arc welding machine allowed us to weld 0.1mm stainless steel bellows with a 0% reject rate."
"Excellent technical support. They helped us optimize our alloy powder feed rate to achieve perfect metallurgical bonding."
