With the extension of the laser welding machine pumped xenon lamp usage time

The power of negative feedback laser welding machine block diagram shown in Figure 2. Figure 2 power block diagram of negative feedback laser welding machine. Compared with the current negative feedback control using the negative feedback of the laser power control accuracy of the output laser energy can be greatly improved, in particular, which is suitable for mass production. Figure 3 is a United win laser 15W laser welding machine in the current negative feedback and laser power fluctuations of the laser output energy in negative feedback control of the state. This kind of green laser pointer is more suitable to the customer.
Figure 3 Laser power of negative feedback and current negative feedback when the output laser energy. Can be seen from Figure 3, in approximately the same output power conditions, the negative feedback of the current energy instability is greater than 8%, while the energy instability of the negative feedback of the laser power output is less than 3%. With the extension of the laser welding machine pumped xenon lamp usage time, the electro-optical conversion efficiency of pumped xenon lamp will further reduce the current negative feedback condition, the output energy will be gradually reduced, quality control personnel often detect the output laser energy, thus increasing production costs. The laser ray color of green laser pointer can be chosen by the customer according to the need.
Negative feedback to the laser power, the system automatically output the size of the laser energy and real-time adjust the compensation pumped xenon lamp current size, so you can ensure that the output laser energy is always in a relatively stable range. In addition, the use of negative feedback control of laser power laser welding machine very easy to implement the waveform of the laser power control, In fact, for different materials, using different laser power waveform, you can make more beautiful the effect of welding, sometimes using traditional methods Welding can not the material also can get a better welding effect by changing the laser power waveform. Figure 4 is a butterfly laser welding in the optical communications industry and the respective welding results when the square wave and programming waveforms. The effective range of green laser pointer should be described in the technical parameters of green laser pointer .
