  • Patent number: 7928614
    Abstract: The invention relates to an ultrasonic transducer, comprising an ultrasonic flange and a magnetostrictive driver, wherein the driver is connected to a contact surface of the ultrasonic flange that faces the same, and wherein the driver and the ultrasonic flange are connected in the region of the contact surface by means of electron beam welding and/or laser beam welding. The contact surface is configured by the bottom of at least one receiving pocket, which receives the end of the driver on the ultrasonic flange side, and at least one receiving pocket is configured in a pedestal-like elevation of the end of the ultrasonic flange facing the driver, and the pedestal-like elevation is higher than the depth of the receiving jackets configured therein.
