Industry-leading solutions for surface engineering and automated manufacturing.
In the era of Industry 4.0, the demand for high-performance surface engineering has skyrocketed. Automatic Plasma Welding (APW), particularly Plasma Transferred Arc (PTA) cladding, has emerged as a critical technology for extending the lifespan of high-value components. As a premier manufacturer and supplier, Shanghai Duomu is at the forefront of this revolution.
The global Automatic Plasma Welding Machine Market is currently undergoing a paradigm shift. Moving away from manual surfacing, industries are now prioritizing repeatability, low dilution rates, and minimal heat-affected zones (HAZ). Our solutions address these needs by integrating advanced sensors and robotic control, ensuring that every layer of hardfacing meets stringent aerospace and nuclear standards.
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 expertise is not just in selling machines, but in providing comprehensive surface engineering solutions.
We pride ourselves on our independent R&D team, which develops, produces, and sells plasma cladding equipment. Our welding machines are renowned for stable performance and the ability to maintain efficient, long-term operation in harsh industrial environments.

Deep dives into the science of hardfacing and cladding.
The Dilution Rate Challenge: In 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 machines are optimized to keep this rate at an industry low (3-5%).
Oil & Gas Downtime: When a choke valve fails, the real cost is downtime—not the component. Our specialized valve cladding machines extend service life by up to 300% in corrosive environments.
Conveyor Reliability: Screw conveyors are frequent causes of unplanned shutdowns. Our DH6-LC501 series provides automatic cladding for screw flights, dramatically reducing wear in cement and mining processing.
