With the development trend of the laser field, the welding process of the laser welding machine is also becoming more and more common, that laser welding machine in the development of electric welding work, if the current size or large, how to carry out the adjustment? Today I will share with you:

If the current is increased, the duty cycle and frequency are maintained without change, the point kinetic energy is increased, and the total laser power is also increased. If the current and frequency are maintained without change, the duty cycle is increased, the point kinetic energy is also increased, and the total laser power is also increased.
If the current and duty cycle do not change, the point kinetic energy does not change, and if the frequency is increased, the total laser power is also increased. How the deviation is not large can be specified according to the optical switch of the beam expanding mirror (the laser of the optical switch should be in the management center of the beam expanding mirror as far as possible, and all normal deviations can not exceed 1MM).
If the deviation exceeds 1MM, to move the laser and fix it again, it is likely that the laser will be disassembled to produce and process a suitable set of hole pitch correction laser parts. On this issue, we do not have to blindly adjust the laser path according to the adjustment of the beam expanding mirror. Once the deviation is too large, the output power of the laser and the actual effect of the laser spot plastic surgery will be greatly affected, so the actual effect of laser welding has a very great harm.
If the method can not deal with the problem that the output power of the laser welding machine is too small, it is not a technical professional maintenance personnel, please do not just break the laser welding machine, contact the laser welding machine manufacturer to carry out after-sales maintenance service. I have a detailed introduction to the way of adjusting the current size of the laser welding machine, and I look forward to you being able to assist you after reading it.
