Main Features of Ultrasonic Metal Welding Machine

Ultrasonic Metal Welding Machines are similar to friction welding, but with differences. 

Ultrasonic welding has a short welding time and operates at temperatures lower than 

recrystallization temperatures. It differs from pressure welding due to the applied static 

pressure, which is much lower compared to pressure welding. However, for most of my

friends,ultrasonic metal welding machines might still be unfamiliar. Let's further introduce 

the knowledge of ultrasonic metal welding machines and their main characteristics.

Main characteristics of ultrasonic metal welding machines:

Welding: Two objects to be welded are overlapped and connected into a solid by ultrasonic 

vibration. The connection time is short, and the connection area does not produce defects

 in the cast structure (surface roughness).

Mold Aspect: Compared with ultrasonic and resistance welding, the mold life is longer,

 requiring less maintenance and replacement time for molds, and is conducive to automation.

Energy Consumption: Ultrasonic welding can be performed between the same metal and 

different metals, with much lower energy consumption compared to arc welding.

Comparison with Pressure Welding: Compared to other pressure welding methods, ultrasonic

 welding requires lower pressure, resulting in deformation of less than 10%, while cold pressure

 welding causes deformation of 40%-90% in workpieces.

Welding Treatment: Ultrasonic welding does not require pre-treatment and post-treatment of the 

welding surface like other welding methods.

Welding Advantages: Ultrasonic welding does not rely on external factors like flux, metal fillers,

 or external heating.

Welding Effect: Ultrasonic welding can minimize the temperature effect on materials (welding area

 temperature does not exceed 50% of the melting temperature of the welding metal). The metal 

structure remains unchanged, making it suitable for applications in the electronics field.

Ultrasonic metal welding machines offer these features that make them a valuable tool for joining 

metals in a precise, efficient, and controlled manner, particularly in industries requiring minimal

 heat input and structural integrity preservation.
