Ultrasonic welding is mainly suitable for copper and aluminum connections. The process requires little energy and is fast. Components joined by ultrasonic metal welding equipment have high strength and excellent electrical conductivity, since the vibrations destroy oxide layers and remove impurities on metal surfaces. Contact resistances, such as those taking place during soldering or crimping do not occur. Reproducibility of the process sequences is important for precise and efficient production with a high degree of quality monitoring. The quality of ultrasonically welded connections therefore heavily depends on application-specific process development. In the laboratory at Herrmann Ultrasonics, we systematically determine the optimum process parameters for your ultrasonic weld task and design the perfect weld system for your production environment.
- Fast and efficient production process
- Low energy input
- High degree of quality monitoring
- Process optimization using a wide range of welding parameters
- Additives such as solder are not required
- Solid and conductive connections without contact resistances
- Ideal for anodes and cathodes in lithium-ion batteries, stranded wires, busbars, and cable harnesses
The Herrmann Family of Ultrasonic Metal Welders
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.
HiS VARIO B is great for the ultrasonic welding of copper or aluminum as part of battery assembly. Designed for either integration into automated equipment, or manual operation, this product provides patented, accurate and repeatable sonotrode alignment and quick tool changes. EtherCAT, PROFINET IO and EtherNet/IP interfaces are available.
For ultrasonic welding aluminum or copper cable to terminals, consider HiS VARIO W. This too is offered as a manual workstation or automation integration. Quick, reproducible tool change and precise sonotrode alignment for quality results across various assemblies. Large gauge cables up to 95 mm2 can be welded.
Terminal welding is addressed by HiS VARIO T. Busbars and power distribution assemblies are quickly adapted in this modular design.
The heart of all Herrmann Ultrasonics’ machines is the ULTRAMETAL digital ultrasonic generator. Intended for intermittent applications, this product is available in 20 and 35 kHz frequencies with power from 1200W to 6200W. Whenever you’re trying to find an ultrasonic metal welder for sale, make sure this is the generator it uses.
