Abstract

New methods of ultrasonic metal welding and characteristics of the welded specimens are studied. For welding of small specimens such as thin wire bonding, the bonding equipments designed using higher vibration frequency and complex vibration welding tips of 90, 120 and 190 kHz are significantly effective. For medium size welding specimens, complex vibration welding tips are also very effective, and one-dimensional complex vibration systems are developed to simplify the complex vibration systems. For welding of large specimens, ultrasonic butt welding methods joining thick metal specimens end to end are effective. Using the methods and large capacity vibration sources and power amplifiers of 5 to 50, 100 kW, thick and large various metal plate specimens are successfully welded. Ultrasonic welding methods using two vibration systems are also very effective, but not mentioned here
