METHOD FOR JOINING COMPONENTS, METHOD FOR JOINING CLOSURE MEMBER TO CONTAINER, AND ULTRASONIC WELDING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a welding/joining method which can meet the change of the work subject of members when the members are subjected to ultrasonic welding/joining and an apparatus for the method.

SOLUTION: In the joining method, components are heat-welded in a prescribed longitudinal direction by the vibration of an ultrasonic vibrator. The joining positions of the components are matched and fixed. The ultrasonic vibrator is vibrated. The components and the ultrasonic vibrator are moved relatively in the longitudinal direction and heat-welded.
