Abstract
A method for soldering or deforming a workpiece, according to which a sonotrode of supersonic welding device is placed on the workpiece to be machined and the oscillation amplitude of the sonotrode is modified. In order to optimize the soldering operation, the oscillation amplitude is reduced according to a pre-determined gradient during a predetermined time t, a characteristic parameter of the workpiece is measured directly or indirectly after time t, and the sonotrode transmits supersonic energy to the workpiece at a predefined constant or essentially constant amplitude during a period of time time t, according to the value of the measured parameter.
