"Customized Finished Plate" is a welding method that uses high-frequency vibration to thermally fuse two workpieces together through intermolecular friction. During this process, the adjustment of pressure has a significant impact on the welding effect. The following is a detailed analysis of this influence:

Firstly, the main function of pressure in the Customized Finished Plate is to conduct ultrasonic vibrations onto the weldment and strengthen the contact surface between the welding heads to make them in close contact, thereby accelerating heat transfer and enhancing the strength and density of the weld. The pressure required for welding different materials varies, so choosing an appropriate pressure value is crucial for the welding outcome.

When the welding pressure is too low, a series of problems will occur. Firstly, the ultrasonic vibration cannot be well transmitted to the welded piece, resulting in insufficient friction between the welded piece and the welding surface. This will cause a large part of the energy to be lost on the surface, making it impossible to form an effective weld. Secondly, too low welding pressure may result in a relatively small sliding resistance at the interface, causing the energy generated by friction to be insufficient to form an effective connection. In addition, low pressure will also lead to less molten material at the welding site, further affecting the welding effect.

On the contrary, when the welding pressure is too high, it will also have a negative impact on the welding effect. Firstly, excessive pressure may lead to the unreasonable use of vibration energy, resulting in excessive friction and weakened frictional movement between the welded parts. This will cause the connection area between the welded parts not to increase but to decrease instead, and the strength of the weld points will also decline. Secondly, excessive welding pressure may cause the tool head to press down too deeply, resulting in the metals at the welding interface interlocking with each other, affecting the relative movement of the interface and thus hindering the further connection of the interface metals. This will lead to the deterioration of the mechanical properties of the welded joint and reduce the welding quality.

In fact, the strength of the welded joint first increases and then decreases with the increase of pressure, which means that there exists an optimal range of welding pressure to achieve the highest welding strength. Within this range, the welding pressure can effectively control the amplitude and frequency of vibration, preventing problems such as burnout of the welding joint or insufficient tensile strength caused by the vibration wave speed being too fast or too slow. Meanwhile, a reasonable welding pressure can also apply pressure to shape the welded joint, thereby ensuring a complete weld structure.

Therefore, in actual operation, it is necessary to precisely control the welding pressure according to the specific welding materials and requirements. Under normal circumstances, the welding pressure should be kept as stable as possible, neither too high nor too low. At the same time, real-time monitoring of the welding effect is also necessary, and the welding pressure should be adjusted in a timely manner to avoid a decline in welding quality due to improper operation.

Furthermore, the current and amplitude of the Customized Finished Plate are parameters directly related to the welding pressure. By adjusting these parameters, the pressure exerted by the welding head on the workpiece can be effectively controlled, thereby further optimizing the welding effect.

To sum up, the adjustment of pressure has a significant influence on the effect of the Customized Finished Plate. In actual operation, it is necessary to carefully consider and precisely control the welding pressure to ensure the best welding quality and effect.
