DEVICE OF ULTRASONIC JOINING FOR METAL AND METHOD OF ULTRASONIC JOINING FOR METAL

摘要

PROBLEM TO BE SOLVED: To provide a device and a method of an ultrasonic joining for metal, by which metallic sheets of different kinds are surely joined.;SOLUTION: Ultrasonic wave is transited by butting two projected parts 1a of an ultrasonic wave horn 1 against one of metallic sheets of different kinds by using a joining device provided with the ultrasonic wave horn 1 for transmitting the ultrasonic wave to layered metallic sheets of different kinds, and the two projected parts 1a which are furnished on the ultrasonic wave horn 1 and are butted against one of metallic sheets of different kinds.;COPYRIGHT: (C)2002,JPO
