This paper give a description of an experimental study of ultasonic welding of ceramics and aluminium or copper. The ultrasonic welding technique can be carried out in many different ways, such as in direct welding of ceramics and metals, the coating of metal on ceramics surface by vacuum deposition, and in application of inserting of activated metals. The ultrasonic welding has made possible to weld various ceramics, such as SiO_2,Al_2O_3,SrO, ZrO_2,SiC, Si_3N_4,to aluminium or copper under the room temperature quickly and easily compared to other welding methods. For example, the ultrasonic welding of Al_2O_3 and aluminium could be finished under the condition of amplitude 23μm of ultrasonic horn top, welding pressure 20MPa, required duration 0.3s. The clean with a forced ultrasonic vibration of contact surface needs no surface treatment. Moreover, the material can be processed easily, and it gives out little heat, and hardly get weakness.
