Abstract

The ultrasonic metal welding is highly used in extensive field due to the possibility for welding of various materials such as new materials, plated structures and etc, and its welding conditions has been diversify. In this paper, one-wavelength tool horn of step type designed for ultrasonic metal welding of dissimilar metal sheets has performed by FEM analysis. FEM analysis is applied to predict the natural frequency of ultrasonic tool horn and use of in the optimal design of ultrasonic horn shape. And the optimal design of one-wavelength step horn is confirmed experimentally using natural frequency analysis system.
