Ultrasonic metal welding machines use high-frequency vibrations to join metal parts together. The working principle of ultrasonic metal welding machine involves several steps:

1.The two metal parts to be joined are placed in contact with each other.

2.A transducer converts electrical energy into mechanical vibrations of high frequency, typically in the range of 20 to 70 kHz.

3.The mechanical vibrations are transmitted through a sonotrode (also known as a horn) that is in contact with one of the metal parts.

4.The vibrations create friction between the two metal parts, causing them to heat up and become plasticized at the interface.

5.The plasticized metal flows together, creating a solid-state bond between the two parts.

6.The vibrations are then stopped, and the welded assembly cools and solidifies.

Ultrasonic metal welding machines are commonly used to join non-ferrous metals, such as aluminum and copper, and can be used to join dissimilar metals as well. They are widely used in the automotive, aerospace, electronics, and medical industries.
