The difference between pre-pressing and pressuring time of capacitor discharge spot welder [CD05]
Dec 21,2023
- Concepts of prepressing and pressurization
Capacitor discharge spot welding machine is a kind of equipment that uses capacitor charge and discharge to realize spot welding. In the process of spot welding, pre-pressing and pressurization are needed.
Prepressing refers to pressing the electrode tightly before spot welding to increase the contact area, thereby improving the effect of spot welding.
Pressurization refers to the process of applying a certain pressure on the electrode to the workpiece after prepressing and charging the capacitor with result that enough heat is generated between the electrode and the workpiece to achieve spot welding.
- Difference between prepressing and pressuring time
Although prepressing and pressurization are both necessary operations, there is a certain difference in the time of the two.
In capacitor discharge spot welding, the prepressing time is usually shorter than the pressuring time. It is because the electrode needs to be pressed tightly during prepressing to improve the contact area, but the charging process has not been carried out at this time. The prepressing time is short.
When pressurizing, it is necessary to charge and apply a certain pressure to generate enough heat to achieve spot welding. So the time for pressuring is generally longer than the time for prepressing.
- The importance of prepressing and pressurization operations
In capacitor discharge spot welding machine, prepressing and pressurization play a very important role.
If the prepressing time is too short, the contact area between the electrode and the workpiece is insufficient, which will affect the spot welding quality. If the pressuring time is too short, it can not generate enough heat to achieve spot welding, which will also affect the quality of spot welding. Therefore, in the use of capacitor discharge spot welding machine, the pre-pressing and pressuring time needs to be adjusted according to the specific situation to obtain the best spot welding effect.
- Conclusion
In short, the operation of prepressing and pressurization in the capacitor discharge spot welding machine are the key steps to achieve spot welding, and the time of the two is different. Reasonable prepressing and pressuring time can improve the effect of spot welding, so as to obtain better welding quality.
