What is laser cladding machine?
Laser cladding machine is a kind of equipment that uses laser technology for cladding (melting and solidification) processing. It uses a high-energy laser beam to melt the metal powder or wire and fuse it with the surface of the substrate to form a new material covering layer by controlling the power, focus and scanning mode of the laser.
What are the main functions of the laser cladding machine?
Cladding repair: Laser cladding machine can melt metal powder or wire through high-energy laser beam to fuse it with the surface of the substrate to achieve surface repair. It repairs damaged parts, fills worn or corroded areas, and increases the wear and corrosion resistance of materials.
Material improvement: The laser cladding machine can clap different kinds of materials on the substrate to achieve material improvement. By adjusting cladding parameters and selecting different materials, the hardness, wear resistance, high-temperature resistance, corrosion resistance, and other characteristics of materials can be changed to meet specific engineering requirements.
Coating Application: Laser cladding machines can also form a coating on the surface of the substrate, providing additional protection and functionality. The coating can improve the hardness of the surface, reduce the coefficient of friction, enhance wear resistance, and can also realize special functions such as heat conduction and insulation.
Customized processing: The laser cladding machine is highly flexible and can be customized according to different needs. By controlling the movement and parameters of the laser beam, complex shapes, and precise dimensions can be processed to meet individual needs.
In short, the laser cladding machine realizes the repair, improvement, and coating application of the material surface through laser cladding technology, and provides enhanced performance and protection for the material. It is widely used in various industrial fields such as aerospace, automobile manufacturing, and energy fields.
What are the important components of the laser cladding machine?
A laser cladding machine usually consists of a laser generator, an optical system, a powder supply device, a scanning control system, and a workbench. The laser generator produces a high-energy laser beam, the optical system focuses the laser beam to the cladding area, the powder supply device provides metal powder or wire, the scanning control system controls the trajectory of the laser beam, and the workbench is used to fix and move the laser beam processed workpiece.
What is the working principle of laser cladding machine?
In the laser cladding process, the laser beam is focused on a small-sized area to generate high temperature, which causes the metal powder or wire to melt rapidly and fuse with the surface of the substrate. With the scanning of the laser beam, it is covered layer by layer to form a uniform and dense covering layer. During the cladding process, the power and scanning speed of the laser can be adjusted as needed to control the thickness and quality of the cladding layer.
