Yantai Xingtai Aluminum Alloy boats: surface treatment Alumi

Aluminum Alloy has high effect on laser, the Aluminum Alloy for proper surface pretreatment, such as anodic oxidation, electrolytic polishing, sandblasting, sandblasting processing etc., can significantly improve the surface absorption of light energy. The results show that the tendency of crystalline crack of aluminum alloy after removing oxide film is larger than that of original aluminum alloy. In order to not only destroy the surface state of aluminum alloy, but also simplify the process of laser welding engineering, the pre welding pretreatment method can be used to increase the surface temperature of the workpiece, so as to improve the absorption rate of the material to the laser.
