Abstract
The ultrasonic welding technique can be carried out in many different ways, such as in direct welding metal/metals. This paper gives a description of an experimental study of the ultrasonic welding of aluminum and cupper at room temperature and water bath, both quickly and easily when compared to other welding methods. When controlling the ultrasonic power, it is thought that the welding characteristic can be guessed. Also, welding in the water bath can be small heat affected zone.
