How the Ultrasonic Welding Process Works
Step 1: Component Positioning
First, you position the battery components to be welded – such as tabs to electrodes or caps to terminals. The welding fixture holds them securely in place.
Step 2: Parameter Adjustment
Next, you set the appropriate air pressure (0.1-0.6Mpa) and power level based on your materials. The system allows quick adjustment for different applications.
Step 3: Ultrasonic Activation
When you initiate the weld, the ultrasonic stack applies high-frequency vibrations to the materials. These vibrations create friction at the interface, generating heat through molecular motion.
Step 4: Solid-State Bond Formation
The materials never melt. Instead, the ultrasonic energy creates a solid-state metallurgical bond as atoms diffuse across the interface. This process completes in <1 second.
Step 5: Quality Assurance
The result is a clean, strong weld with no contamination, no heat damage, and excellent electrical conductivity – ideal for battery applications.
