The tab ultrasonic welding machine utilizes high-frequency vibration energy to achieve molecular bonding between metals in a solid state. Unlike traditional laser welding and other melting methods, ultrasonic welding generates no high heat that could degrade tab material properties.
This process effectively maintains the mechanical and electrical properties of the tab, ensuring stable current transmission during battery charging and discharging while reducing energy loss.
This equipment is widely used in tab welding processes for various lithium battery types:
The machine covers both pre-welding and final welding stages, making it an indispensable key equipment in new energy battery manufacturing.
