In the contemporary landscape of surface engineering, Soudage Au Plasma (Plasma Transferred Arc - PTA) has emerged as a transformative technology for industrial remanufacturing and wear resistance. Unlike traditional welding methods, PTA utilizes a constricted plasma arc to melt both the base material surface and a filler material (usually in powder form). This process creates a metallurgical bond with exceptionally low dilution—often below 5%—which is critical for maintaining the high-performance properties of expensive alloy overlays.
As industries worldwide push for "Circular Economy" models, the demand for Custom Soudage Au Plasma solutions has surged. From the North Sea oil rigs requiring corrosion-resistant valves to the open-pit mines in Australia needing wear-resistant screw conveyors, PTA is the global standard. The current technical roadmap focuses on Digital Twin integration and Closed-Loop Feedback Systems, where real-time sensors adjust the arc voltage and powder feed rate to ensure 100% deposit consistency.
Optimized for abrasive and erosive environments in mining and cement industries.
Precise control over heat input ensures the alloy's chemical purity remains intact.
Fully compatible with multi-axis CNC and robotic arms for complex geometries.
Our PTA cladding and laser systems are deployed across diverse high-stakes environments:
Hardfacing plowshares and harvesters for extended service life in sandy soils.
Precision surfacing of turbine blades and landing gear components using micro-plasma.
Internal and external cladding of valves and drill stabilizers for deep-sea exploration.
Repairing large-scale forging dies and continuous casting rollers.
Shanghai Duomu represents the pinnacle of China's specialized cladding equipment supply chain. For over a decade, we have leveraged Shanghai's high-tech industrial cluster to integrate world-class power electronics with proprietary arc control algorithms. This allows us to offer Information Gain to our clients—not just equipment, but the specific welding parameters and alloy combinations that maximize ROI.
