How to solve the problem that the laser welding machine suddenly does not emit light

Source:  Release time:2021-01-20

The laser welding machine has the advantages of high energy density, small deformation, narrow heat-affected zone, high welding speed, easy automatic control, and no subsequent processing, and abandons the traditional welding method. If the laser welding machine has been used for a period of time, and the intensity of the light output is constantly attenuating, it may be caused by the aging of the components of the laser light source.

If the laser button is normal, open the CNC display interface to check whether the setting is continuous light output, if not, change it to continuous light output. Observe whether there is a laser display on the display interface and whether the number of laser outputs is normal when the display interface is running. After replacing the main board of the welding machine, observe whether it is normal. If it still does not emit light, replace the shutter.

If the laser welding machine has stable light output and stable light output power before, it may be caused by the following two problems: the control system such as the software board has a problem; the optical path moves, or the power supply, laser generator, cooling system and other hardware are out of order. question. Observe whether the light on the display screen of the welding machine is normal. If the laser welding machine can be converted but no light is displayed during welding, first check whether the laser button of the CNC part is turned off. If it is turned off, turn on the laser button.
