Background

In the structure of the current common automobile door panel, the automobile door panel is mostly formed by combining a plurality of groups of plastic parts, the plurality of groups of plastic parts are fixed into a whole by using different processes, and ultrasonic welding is one of the processes. The ultrasonic welding process is that 50/60 Hz current is converted into 15, 20, 35 or 40 KHz electric energy by an ultrasonic generator, the converted high-frequency electric energy is converted into mechanical motion with the same frequency again by a transducer, and then the mechanical motion is transmitted to a welding head by a set of amplitude-changing rod devices. The horn transmits the received vibrational energy to the joint of the work pieces to be welded where it is frictionally converted to heat energy to melt the plastic. Ultrasound can be used not only to weld rigid thermoplastics, but also to process fabrics and films.

Linear vibration friction welding uses frictional heat energy generated at the interface of two workpieces to be welded to melt plastic. The heat energy comes from the reciprocating movement of one workpiece on the other surface under a certain pressure with a certain displacement or amplitude. Once the desired degree of welding is achieved, the vibration is stopped while still allowing some pressure to be applied to the two workpieces, allowing the just-welded portion to cool and solidify, thereby forming a tight bond.
