How does Manhart (Guangdong) CNC Machine Tool Co., Ltd.’s surround type dual platform laser welding machine cope with welding of different materials?

The surround type dual platform laser welding machine adopts a series of strategies and measures to ensure welding quality and efficiency when dealing with welding of different materials. Here are some key aspects:
Firstly, according to the characteristics of different materials, laser welding machines need to adjust parameters such as laser power, spot size, and welding speed. For example, for high reflectivity materials such as aluminum alloys, it may be necessary to increase laser power to ensure sufficient energy input; For materials with high thermal conductivity, it may be necessary to adjust the spot size or welding speed to control the heat affected zone.
Secondly, the treatment of the material surface is also crucial. Before welding, it is necessary to clean and polish the surface of the workpiece to remove impurities such as oxides and oil stains, ensuring that there is no contamination at the welded joint. For certain special materials, such as stainless steel or titanium alloys, pre-treatment such as sandblasting or pickling may be required to improve the quality of welded joints.
In addition, selecting the appropriate protective gas is also crucial. Protective gas can not only prevent oxidation and pollution in the welding area, but also affect the shape and stability of the welding pool. According to the properties of the material and welding requirements, protective gases such as argon, nitrogen, or mixed gases can be selected.
For the issue of differences in thermal expansion coefficients of different materials, laser welding machines reduce residual stress and deformation of welded joints by precisely controlling the heat input and cooling rate during the welding process. This may require parameter optimization based on the physical properties of the material and the characteristics of the welding process.
Finally, regular maintenance and calibration are also important steps to ensure that laser welding machines can handle welding of different materials. Regular inspection and maintenance of equipment can ensure the stability of the laser, cleanliness of optical components, and accuracy of mechanical components, thereby ensuring welding quality and efficiency.
In summary, the surround type dual platform laser welding machine can effectively cope with the welding challenges of different materials and achieve high-quality welding effects by adjusting welding parameters, optimizing material surface treatment, selecting appropriate protective gases, controlling heat input and cooling speed, and regular maintenance and calibration measures.
