High speed laser cladding system



Product description:


In the conventional laser cladding process, laser energy is mainly used to melt the base material to form a molten pool. The powder is poured into the molten pool and melted, and then solidified to form a protective coating.

 
The ultra-high-speed laser cladding technology essentially changes the melting position of the powder, so that the powder meets the laser and melts above the workpiece, and then uniformly coats the surface of the workpiece. Its cladding rate can be as high as 20-200m/min. Due to the low heat input, this technology can be used for surface cladding of heat-sensitive materials, thin-walled and small-sized components, and it can be used for brand-new material combinations, such as aluminum-based materials, Preparation of coatings on titanium-based materials or cast iron materials. Since the surface quality of the coating is significantly higher than that of ordinary laser cladding, it can be applied only by simple grinding or polishing. Therefore, the waste of materials and subsequent processing are greatly reduced. Ultra-high-speed laser melting is in terms of cost, efficiency, and thermal impact on parts. Covering has an irreplaceable application advantage.








Technical advantages


Efficient and low cost


• Cladding line speed 20-200m/min

• Cladding efficiency 0.8-1.2m²/hr (depending on coating thickness)

• The powder utilization rate can reach more than 95%

• There is no need for subsequent turning processing, and it can be directly ground or polished


High quality and adaptability


• Hard stainless steel corrosion-resistant coating has a hardness above HRC50, no corrosion points

• The hardness of the super hard wear-resistant coating can reach above HRC65, which is suitable for various surface friction and impact wear

• Applicable coating thickness 0.05-1mm

• High surface quality, the surface roughness can reach Ra25μm after cladding

• Suitable for iron-based, nickel-based, cobalt-based, copper-based, amorphous, composite materials and other material systems


Low heat input


• Low laser power requirements
• Little impact on the substrate, small deformation of parts
• The best solution for surface cladding of parts with large aspect ratio, thin-walled and heat-sensitive materials
