Products Description

Metal powder welding is an advanced composite process that combines additive manufacturing and welding. Its fundamental principle involves using a high-energy heat source (such as plasma arc, laser, or electron beam) to simultaneously melt the fed metal powder and the surface of the workpiece substrate, forming a metallurgically bonded cladding layer or welded joint. This technology combines the robustness of welding with the flexible forming capabilities of additive manufacturing.

Performance Characteristics

High Bonding Strength: Achieves complete metallurgical bonding with high strength and resistance to peeling.
Low Dilution Rate: Enables precise control of heat input, minimizing the melting of the substrate material. The dilution rate is typically below 5%, effectively preserving the properties of the cladding material.
Flexible Shaping: Allows layer-by-layer accumulation of complex three-dimensional structures, making it suitable for curved surface repairs and the manufacturing of irregular-shaped parts.
Wide Material Compatibility: Supports the use of various metal powders, including stainless steel, nickel-based alloys, cobalt-based alloys, and titanium alloys.
Small Heat-Affected Zone: Concentrated energy reduces the impact on the overall thermal deformation of the workpiece.
High-Performance Coatings: Enables the creation of functional surfaces with properties such as wear resistance, corrosion resistance, and high-temperature oxidation resistance.

main application
