What Are the Precautions for Using Mold Laser Welding Machine
With the development of laser welding machine getting better and better, it is faster and more convenient to repair mold with mold laser welding machine than ever before, but it is still a technical activity, which requires a lot of experience accumulation to control it. So, what precautions do we usually have when operating the mold laser welding machine to repair the mold?1. When repairing the mold with the mold laser welding machine, observe the mold and repair welding with a microscope, and observe with both eyes at the same time, so that the specific situation of the mold can be observed during observation.2. The welding wire should also be selected correctly during operation, because only the welding wire is selected correctly can the mold be repaired (the diameter of 0.2-0.8 can be melted). If it is not used correctly, the repair effect of the mold will be affected, and even the mold cannot be repaired.
3. The materials of different molds are different, including galvanized, beryllium copper and aluminum. Only by understanding the material of the mold can we set the corresponding parameters to achieve the repair welding effect.4. The mold laser welding machine must be protected by argon, and the program should be set to output argon first and then laser to prevent oxidation of the first pulse laser during continuous processing.5. When the mold is laser welded, the most common is that there are bite marks around the welding part. The welding part shall be covered by laser empty beating to prevent the occurrence of bite marks. The spot exceeds the welding position (0.1mm).
6. Parameters that can be set for the power supply of the mold laser welding machine: current 50-400a, pulse chamber 0.1-20ms, frequency car 0-50. When welding the mold normally, the processing parameters are as follows: current: 90-120, pulse width: 4-6; The frequency is 5-10. When welding beryllium copper and aluminum, the current increases by 30-50a7. CCD system (camera system) can be used for monitoring. The function is that in addition to the operator's observation from the microscope, non operators can watch the whole burning process through the display screen of the camera system.
