Ultrasonic welding of non-ferrous metals (such as copper and aluminum) is a mature welding technology that has been tested in practice for many years in the industry. Ultrasonic welding is extremely fast, it only takes 1 to 3 seconds, and the time varies slightly depending on the size of the welded joint. Compared with other welding processes, when ultrasonic welding technology is used, the temperature of the joint is smaller, so it will not reach its melting point. This gives it many advantages that other connection technologies do not have. It will not damage other nearby materials, such as wire insulation. Including simple wire and bus connection, wiring harness and contact welding in the automotive and electronic fields, as well as special applications for enameled winding wires, films and sheets, and in the transition area to solid materials, the joints will not be embrittled . High welding strength is produced by the relaxation process of the first two atomic layers of the parts to be welded. The welding method is similar to diffusion welding, and its application in the metal field is diverse.

Plastic ultrasonic welding means that all thermoplastic materials are connected to each other in the weld. Under the action of force and energy, longitudinal vibration and torsion welding are introduced into the plastic at a frequency of 20kHz’30kHz’35kHz’40kHz, 50KHZ, and 4μm to 60μm welding head amplitude energy. The ultrasonic vibration is welded together by the structure of the weldment and the mold. People call these special structures in weldments the conduction angle. The direct contact point between the contour of the joint surface and the thermoplastic component is focused by transmitting the high-frequency energy of the fusible wire, and the deformation occurs in a targeted manner. The friction of the contact surface generates heat and melts the material.

The main function of the ultrasonic cutting process is to split the connected parts. The high frequency vibration per second can reduce the pressure on the object to be cut. In this way, a neat and clean cutting surface can be formed. In practical applications, it is divided into two processes, separate welding and cutting. Separation welding is mainly used in the fields of textiles, films and non-woven fabrics. Ultrasonic cutting can be used not only in the food industry, but also in solid materials such as rubber, foam and artificial leather.
