Those who know ultrasonic metal welding machine should know that ultrasonic metal welding machine is similar to friction welding, but there are also differences. Ultrasonic welding time is short, temperature is lower than recrystallization; Due to the static pressure applied, it is also different from pressure welding. It is much smaller than pressure welding. But for most of my friends, ultrasonic metal welding machine is still quite strange. Next, let's popularize the common sense of ultrasonic metal welding machine and the main features of ultrasonic metal welding machine.

Main features of ultrasonic metal welding machine:

1. Welding: Overlap two objects to be welded and connect them into solid by ultrasonic vibration. The connection time is short, and there is no casting structure (rough surface) defect at the connection part.

2. Mold: Compared with ultrasonic welding and resistance welding, mold has a long life, less time for mold maintenance and replacement, and is easy to realize automation.

3. In terms of energy consumption: ultrasonic welding can be carried out between the same metal and different metals, which is much less energy consumption than electric welding.

4. Pressure welding comparison: compared with other pressure welding, ultrasonic welding requires less pressure, with deformation less than 10%, while the deformation of cold pressure welding workpiece is 40% - 90%.

5. Welding treatment: ultrasonic welding does not require pre-treatment and post welding treatment on the welding surface like other welding.

6. Welding advantages: ultrasonic welding does not require external factors such as flux, metal filler and external heating.

7. Welding effect: ultrasonic welding can reduce the low level of temperature effect of materials (the temperature of welding area is not more than 50% of the melting temperature of welding metal), and the metal structure will not change, so it is very suitable for welding applications in the electronic field.
