One form of fusion welding process is ultrasonic welding, where similar and dissimilar materials can be joint effectively. All industrial applications, including those in the aerospace, automotive, medical, electrical, packaging, and textile industries, rely heavily on USW. Here we can easily join thin wire, foils and sheets with high quality welded joint without using any filler material, preparation of the surface and a shielding gas. The strength and quality of the joints were assessed using a variety of process variables, including vibration amplitude, weld pressure, and weld duration. With certain traits, different joint designs were feasible. For metal to metal weld plastic deformation occur and for plastic to plastic weld diffusion occur between the work piece's interface due application of vibration energy. The welding method is excellent for both hard and soft materials since it moves quickly and takes little time to dry. Ultrasonic vibrations have an impact on the joint's quality. The workpieces that were to be connected were pressed together and subjected to ultrasonic vibrations (range between 20 and 40 kHz). This essay tries to provide a survey of the literature on ultrasonic welding.
