With the improvement of technical strength, the production method of the manufacturing industry at this stage has changed from the traditional capacitive gate production and processing to the laser capacitive gate production and processing, in order to improve the welding efficiency and the actual welding effect. However, the specific use of the whole process will still encounter various problems harm the actual effect of welding, below I on the laser welding machine welding cracks how to do and some of the common problems of the disposal of a simple interpretation.
Laser welding machine welding cracks: maintenance gas pressure is too large, can reduce the total flow of maintenance air to deal with. If the cooling rate of the workpiece is too fast, the temperature of the cooling circulating water on the fixture should be adjusted to increase the temperature of the water.
The workpiece is not clean and tidy, encounter such things must clean the workpiece again. The matching gap between the workpiece is too large or there are rough edges, and the processing accuracy of the workpiece should be improved. Laser welding machine welding melting depth is not enough. The laser kinetic energy is insufficient, and the pulse width and current flow can be increased to deal with it.
If the defocus of the condenser is not correct, the defocus amount should be adjusted to the part close to the focus (but not caused by splashing). The laser beam of the laser welding machine is weak, the cooling water source is polluted or the cooling circulating water is not removed for a long time, and the cooling circulating water can be removed and the filtered UV glass test tube and xenon lamp can be treated.
