In the ultrasonic welding process, the amplitude of the ultrasonic welding equipment plays a decisive factor in the impact of welding. Usually, we select the appropriate amplitude range according to the products to be welded. Next, Nico’s editor will lead you to learn some ultrasonic welding knowledge.

Amplitude is one of the very important parameters in the ultrasonic welding machine. It has a decisive effect on the size of the friction power. It also has a very close relationship with the oxide film on the welding surface, the frictional heat generation of the bonding surface, and the plastic flow layer. Therefore, it is very important to choose the right amplitude. The amplitude range is generally from 5 to 256 nanometers. The smaller the power of the welding machine, the higher the vibration frequency, and the lower the selected amplitude; when the weldment is thinner or the hardness is lower, a lower amplitude needs to be selected. The reason for this is that the magnitude of the amplitude is directly related to the moving speed of the weldment on the contact surface, and the relative moving speed determines the friction power, plastic flow and temperature.
