When the mold laser welding machine performs mold repair, it is necessary to pay attention to how to meet the repair accuracy and repair quality. The control system of the mold laser welding machine plays a key role.
1. The mold laser welding machine should use a 10X or 15X microscope to monitor the operation.
2. The power supply of the mold laser welding machine can adopt the waveform adjustable function, which is suitable for welding of different materials. Such as: die steel, stainless steel, beryllium copper, aluminum, etc.
3. The CCD system (camera system) can be used for monitoring. The function is: in addition to the operator’s observation from the microscope, non-operators can watch the entire welding process through the camera system’s display screen. This device is beneficial to non-operating The technical training of personnel and exhibition demonstrations have played a very good role in promoting the promotion of laser welding technology.
4. It can melt welding wires of different diameters, from 0.2-0.8 in diameter.
5. The mold laser welding machine must be protected by argon, and the program must be set to emit argon first and then laser to prevent oxidation in the first pulse laser during continuous processing.
6. The parameters that can be set for the power supply of the TFLASER mold laser welding machine: current 50-400A, pulse width 0.1-20MS, frequency 0-50, the processing parameters of normal welding mold are as follows: current: 90-120; pulse width: 4-6; Frequency 5-10. When welding beryllium copper and aluminum, the current increases by 30-50A

7. When the mold is laser welded, the most common is that there are bite marks around the welding part, and the welding part should be covered by the method of laser blown, which may cause bite marks to prevent the appearance of bite marks. It is sufficient if the light spot exceeds the edge of the welding position by 0.1mm.
