초록

The Ultrasonic metal welding is used in the solid-phase welding method at room temperature or low temperature state.
In welding process, the high frequency vibration energy is delivered to the welding part under the constant pressure for welding.
In this study, we aimed to design and manufacture a 40,000 Hz band horn through finite element analysis. By performing modal analysis and harmonic response analysis, the modal analysis result is that the horn frequency was 39,599Hz and the harmonic response result that the horn frequency was 39,533Hz. These results were similar. In order to observe the designed horn's performance, about 4,000 voltage data was obtained from a light sensor and was analyzed by FFT analysis using Origin Tool. The result RMS amplitude was approximately 8.5㎛ at 40,000Hz, and maximum amplitude was 12.3㎛.
Using this manufactured horn along with an ultrasonic metal welder and tension tester, the weldability of Cu sheets was evaluated. The maximum tensile force was 66.53 N in the welding condition of 2.0 bar pressure, 60% amplitude, and 0.32s welding time. In excessive welding conditions, it was revealed that weldability is influenced negatively.
