Strategic Insight into High-Energy Surface Engineering
Plasma Arc Spray (and specifically Plasma Transferred Arc - PTA) represents the pinnacle of thermal surfacing. Unlike traditional welding, PTA offers a concentrated heat source that minimizes the Heat Affected Zone (HAZ), ensuring that the base material retains its structural integrity while receiving a superior protective layer.
Our custom solutions achieve dilution rates as low as 5%, a critical factor in maintaining the hardness and corrosion resistance of the cladding alloy. This is essential for components in the petrochemical and nuclear sectors where material purity is non-negotiable.
Integrating 6-axis robotic arms with our plasma systems allows for complex geometry surfacing. Whether it is a turbine blade or a spherical valve seat, our technology ensures uniform coating thickness and zero-defect deposition.
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 independent R&D team develops, produces, and sells plasma cladding machine equipment designed for long-term, high-efficiency operation.
