Reasons affecting the power decline of laser welding machine portable:
1. The speed of the welding machine has a great influence on the power of the laser welding machine,
and the speed of the welding machine is proportional to the power of the laser welding machine.
At the same time, the quality of the welding machine is related to the quality of the laser beam,
but also related to the characteristics of the laser beam focusing system, that is, the size of the focused laser beam has a great impact on the quality of the laser.
2. The distance between the nozzle and the distance between the workpiece and the nozzle will also affect the power of the laser welding machine.
Too long distance will cause unnecessary waste of kinetic energy, too short distance will affect the diffusion ability of spatter welding machine products.
The proper distance is 0.8 mm. In addition, laser welding machine machine mainly
through the following adjustment can weld machine surface uneven workpiece, and in the process of operation nozzle and workpiece height should always be the same.
3. The focusing position will affect the welding machine accuracy, especially the focus diameter.
The focal spot diameter should be as small as possible to produce narrow slits,
and the focal spot diameter is proportional to the focal depth of the focusing lens, and the smaller the focal depth, the smaller the focal spot diameter.
4. Auxiliary gas, auxiliary gas and gas pressure will also affect the power of laser welding machine,
if the thickness of the material increases or the welding machine speed is slow,
the gas pressure should be appropriately reduced, the use of low pressure welding machine can prevent edge welding machine frosting.
