PROBLEM TO BE SOLVED: To provide a device and method for welding, or cutting, and sealing by means of ultrasonic waves with a very simple and inexpensive system without using a sacrifice film.SOLUTION: In the device and method for welding workpiece layers 10, 12, a feed device 18 is activated with designated adjusting force without activating ultrasonic waves, and a sonotrode 14 is advanced in a direction of an anvil 16. Then, the sonotrode 14 activates when the adjusting force is lowered. Further, the sonotrode 14 can be activated and deactivated on the basis of activating and deactivating signals D, and it is possible to solve by improving the adjusting force. |
