ultrasonic spot welding machine
Product Description
Ultrasonic Metal Welder Pouch Cell Welding Machine is designed for battery electrode bonding. In the processing schedule, the foil-to-tab weld gathers all anode and cathode foils inside the cell and joins them to tabs, allowing energy transfer to an external source. This robust joining process meets requirements for high joint strength, low electrical resistance, and minimal inter-metallic layers.
The machine utilizes ultrasonic vibration (typically 20khz, 25khz, or 40khz) to rub tab-to-foil layers together under pressure. This scrubbing action removes oxides and contamination, creating smooth, clean surfaces that form a solid-state weld under moderate heat and pressure.
