MSK-UW-D2000W Dual-Station 2000W Ultrasonic Metal Welder with Sliding Rail Fixture for Electrode Sheet Welding
The MSK-UW-D2000W 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 the fabrication of Li-ion pouch cells within research and development laboratories. Its dual-station design separates anode and cathode welding processes, allowing independent adjustment of welding parameters to optimize quality and efficiency for each electrode type.
Equipped with a sliding rail fixture, this system facilitates the precise positioning and welding of pouch cells and tabs, accommodating configurations with same-side or two-side extrusion. The ultrasonic frequency is fixed at 20 kHz, delivering up to 2000 watts of adjustable ultrasonic power, capable of welding stacks of up to 25 layers. The system includes two standard welding heads and bases pre-installed for both aluminum and copper current collectors.

Typical Applications
This ultrasonic welder is primarily used in battery research laboratories for welding electrode tabs made of copper and aluminum onto current collectors in Li-ion pouch cells. It supports welding of multiple layers, enabling fabrication of complex electrode stacks. The system is also adaptable for welding other metals such as gold, iron, nickel, and silver by adjusting welding power.
Configuration & Operating Notes
The system includes one set of welding heads and bases pre-installed for aluminum and copper current collectors. The sliding rail fixture accommodates pouch cells with either same-side or two-side tab extrusion. Pneumatic control requires an external air compressor supplying 85 psi; this is not included. If using a gas cylinder instead of an air compressor, a two-stage pressure regulator must be installed to ensure safe operation within the required pressure range.
