Ultrasonic welding is an industrial process whereby high-frequency ultrasonic acoustic vibrations are locally applied to work pieces being held together under pressure to create a solid-state weld. It is commonly used for plastics and metals, and especially for joining dissimilar materials.

Learn how ultrasonic metal welding works and the processes of ultrasonic spot welding, wire bonding, tube sealing, seam welding and wire splicing.

2022年9月12日 · Ultrasonic welding is an effective welding process that delivers quality welding joints, ease of operation, and safety. While useful, it requires high precision, accuracy, and technical expertise. On this account, this article talks about the …

2023年11月30日 · The technique, ultrasonic welding, used ultrasonic vibration and pressure to bond metals together and required less energy than conventional welding. Ultrasonic metal welding developed during the 1950s through the 1990s as the electronics used in the equipment became more sophisticated and computers could control the process.

2025年1月21日 · For metals, the vibrations and pressure cause plastic deformation at the contact surfaces, allowing metal atoms to bond without melting. For plastics, the vibrations generate heat through friction, melting the interface, which then solidifies under pressure to form a strong weld. ... Ultrasonic Welding: Ultrasonic welding has lower operational ...

Ultrasonic welding makes it possible to assemble metal components, particularly copper, aluminium and other non-ferrous metals (nickel, brass, etc.) that are difficult to weld using traditional methods. It ensures a true connection and mechanical strength combined with excellent electrical and thermal conductivity.

Our line of ultrasonic metal welders is ideal for welding battery components, cables, and terminals in the automotive, electronics, and energy sectors. At Herrmann Ultrasonics, we produce specific machines optimized for each of these tasks.

Ultrasonic welding is a solid state joining process that uses high frequency ultrasonic acoustic vibrations, applied locally to workpieces that are held together under pressure. Used for both plastics and metals welding, this technique is able to join dissimilar materials.

Sonics and Materials, Inc. manufactures ultrasonic metal welding systems in frequencies of 40 kHz, 20 kHz and 15 kHz with available power supplies ranging from 800 to 6000 watts. Sonics has been a world leader and innovator in ultrasonic welding for over five decades.

2023年9月11日 · You can define ultrasonic welding as a process of joining two parts (metal or thermoplastic) using the localized application of ultrasonic acoustic vibrations and pressure to generate frictional heat and bonding.
