Products Description
The XW-4008G3 battery tab welder is designed for single-layer foil and single-layer tab welding in winding processes, making it suitable for both anode and cathode applications. (It also supports multi-layer spot welding with varying power configurations. For more details, please contact us.)
Equipment Working Principle:
The transducer converts high-power ultrasonic frequency oscillation signals into mechanical energy of the corresponding frequency. This energy is then applied to the interface of the metal sheets that need to be fused. The instantaneous heating of the metal sheets activates the particles within the metal lattice, enabling the molecules in the sheets to interpenetrate and fuse together.
Key Components:
The metal welding machine primarily consists of an ultrasonic generator, transducer, mold, pneumatic components, and a frame.
