Abstract

Welding characteristics of ultrasonic plastic welding using two 27 kHz complex vibration systems vibrating in elliptical locus are studied. Complex vibration systems consist of one dimensional longitudinal to torsional complex vibration converter 20 mm in diameter, a stepped horn and a 27 kHz bolt-clamped Langevin type PZT longitudinal transducer. Using complex vibration welding tip, two-dimensional vibration stress can be induced in welding specimens. Welding specimens used were joined successfully by comple vibrations with smaller total vibration velocity amplitude and smaller deformation of the specimens compared with linear vibration
