Material changes before and after ultrasonic welding

As shown in the figure above, ultrasonic welding is a type ofSolid-state connection process。 Two metal workpieces are therePressureAndHigh-frequency mechanical vibrationUnder the combined action of these two elements, intense friction occurs at the contact interface, breaking the surface oxide layer and contaminants, allowing pure metal atoms to diffuse and form intermolecular bonds, thereby achieving a strong solid-state bond.

Ultrasonic welding is completed according to the following process.
