摘要

Conventional ultrasonic welding uses vibrations with a one-dimensional linear locus. Because the vibration energy is small, this method suffers from the drawbacks that the weld strength is low and variable depending on the installation direction of the welding sample. Our previous studies have revealed that the weld strength can be improved by using vibrations with a two-dimensional planar locus. However, the question of whether welding using planar vibration could be achieved in a short weld time and the relationship between the installation direction of the welding sample and the weld strength remained unclear. Therefore, these issues were addressed by the investigation described in this paper. Consequently, we demonstrated that welding using planar vibration reaches a high strength in a shorter weld time than conventional linear vibration and that stable welding can be achieved independently of the installation direction of the welding sample.
