| In ultrasonic welding, a horn (also called a sonotrode) is used to apply high-frequency vibrations to the parts being welded. There are several types of horns used in ultrasonic welding, including: Tapered horns: These horns are used for general-purpose welding and are the most common type of horn used in ultrasonic welding. They have a gradually decreasing diameter from the base to the tip, which helps to focus the ultrasonic energy. Stepped horns: These horns have multiple diameters along their length, which can help to distribute the ultrasonic energy more evenly across the part being welded. They are often used for parts with irregular shapes or for welding multiple parts at once. Flat-face horns: These horns have a flat tip and are used for welding parts with flat surfaces. They distribute the ultrasonic energy more evenly across the surface of the part being welded, which can help to prevent damage or deformation. Booster horns: These horns are used to increase the amplitude of the ultrasonic vibrations. They are placed between the ultrasonic generator and the sonotrode, and they can help to amplify the energy of the vibrations, allowing for more efficient and effective welding. Cylindrical horns: These horns have a cylindrical shape and are often used for welding pipes or other cylindrical parts. They can help to evenly distribute the ultrasonic energy around the circumference of the part being welded. The choice of horn type depends on the specific application and the geometry of the parts being welded. Each type of horn has its advantages and disadvantages, and selecting the appropriate horn can help to ensure a successful and efficient welding process. Choosing a horn types is sometimes difficult. Horn types should be chosen for the right reasons.
