MSK-UW-D800W Dual-Station 800W Ultrasonic Metal Welder with Sliding Rail Fixture, 40KHz, Max 15 Layers
The MSK-UW-D800W ultrasonic metal welder is engineered to address the challenges of welding multiple layers of copper and aluminum electrode sheets and tabs onto current collectors, a critical step in fabricating Li-ion pouch cells in research and development laboratories. It features a dual-station design that separates anode and cathode welding processes, allowing independent adjustment of welding parameters for each station to optimize weld quality and process flexibility.
This system includes a fixture mounted on a sliding rail, enabling smooth lateral movement to accommodate various pouch cell configurations with same-side or two-side extrusion tabs. The ultrasonic welder operates at a frequency of 40 kHz with a maximum output power of 800W, capable of welding up to 15 layers of electrode sheets. The touch-screen controller supports preset welding programs for aluminum and copper, with the ability to store up to four recipes per metal type, and allows power adjustment to weld other metals such as gold, iron, nickel, and silver.

Typical Applications
This ultrasonic welder is primarily used for welding nickel and aluminum tabs onto copper or aluminum current collectors during the assembly of lithium-ion pouch cells. It is suitable for research and development environments requiring precise control over welding parameters for different electrode materials and layer configurations.
Configuration & Operating Notes
The system includes two standard welding heads and a pre-installed welding base compatible with both aluminum and copper current collectors. Pneumatic control requires an external air compressor providing 85 psi; a gas cylinder may be used only if equipped with a two-stage pressure regulator to ensure safe operation within specified pressure limits. Welding programs can be customized and stored for different metals and layer counts. Optional accessories and certifications can be requested separately.
