Laser welding machine for aluminum and aluminum alloy welding
The main difficulties of laser welding machine for aluminum and aluminum alloys are as follows.
(1) because the workpiece surface at the beginning of the very high reflectivity (more than 90%), the reflectivity is not stable;
(2) with the increase of temperature, hydrogen in the solubility of aluminum increases rapidly, there are generally pores in the weld.
Therefore, when such materials are welded, the workpiece surface needs to be pretreated and high-power laser is needed.
Continuous laser welding machine can weld aluminum and aluminum alloy.
