Utilizing the Heat Generated by 20Khz Ultrasonic Vibration to Achieve Welding of Aluminum Copper Metal Materials

 
Principle: 
 

The working principle of ultrasonic metal welding is to use ultrasonic vibration to transfer to the metal joint, generating local frictional heat. The frictional heat between metal joints causes an increase in the surface temperature of the material. When the temperature reaches the melting point of the metal, it will melt and form a weld. The vibration frequency of ultrasonic waves is usually between 20 kHz and 60 kHz, and the appropriate frequency can be selected based on the required welding materials and applications.

Advantages:

1. Ultrasonic metal welding can complete the welding process in a relatively short time because the vibration of ultrasonic waves can quickly generate heat.
2. Due to the absence of open flames and arcs during the welding process, there will be no significant oxidation, slag, or splashing.
3. Ultrasonic welding usually does not require the use of filler materials or additives, thus maintaining the purity of the metal material.
4. Due to the small heat affected area during the welding process, it can reduce thermal damage to surrounding materials.

Ultrasonic metal welding is widely used in many fields, including automotive manufacturing, electronic equipment manufacturing, aerospace, and medical equipment. It can be used for welding various metal components, such as battery cells, electronic components, wire connections, etc.
It should be noted that ultrasonic metal welding has high requirements for metal materials and requires the welding material to have a certain degree of plasticity. In addition, the metal surface needs to be cleaned and treated before welding to ensure good welding quality.
