Lithium battery welding, copper foil and nickle sheet welding --- Ultrasonic Metal Welding Machine

Advantage of Ultrasonic metal welding:

• No need solder and external heating, does not deform due to heat, does not have the residual

stress, not only welding same metal, but also can weld between the different metals.

• Suitable for non-melting, non-fragile metal materials, good electrical conductivity after welding,

extremely low or nearly zero resistivity. low requirements for welding metal surface, and also be

suitable for oxidation or electroplating.

• Short welding time, no flux, no gas,no solder, no spark, environmental protection and safety.
• Unique structure design, easy welding head changing.
• Imported qualified components to ensure the stable operation of equipment.

There are many materials joining requirements in battery manufacture. Depending on the size, type, and capacity, these include both internal and tab-to-terminal connections, can and fill plug sealing, and external connections. Several joining options can be considered including ultrasonic , resistance, and laser welding. Ultrasonic welding is most often used to join the internal electrode battery materials which are typically constructed of thin foils of copper and aluminum. The remaining joins - including connections inside the can, and external terminal tab connections - are suited to both resistance and laser welding. The decision to use one technology or the other is determined both by the type of weld required and production requirements. Laser welding is the joining technology of choice for can and plug applications (seam sealing).
