Single Side Automatic Battery Pack Spot Welding Machine

Single Side Automatic Battery Pack Spot Welding Machine is designed for cylindrical lithium battery pack nickel strip spot welding and assembly. It is suitable for 18650, 21700, 26650, 32650 and similar cylindrical cell packs used in e-bike batteries, scooters, power tool packs, energy storage modules and customized battery pack production.

This single-side automatic version is a practical automatic spot welding platform for factories that need stable welding of one side of the battery pack before turning, transfer or next process.

Machine Function

The machine is based on a microcomputer automatic processing platform. Compared with manual spot welding, automatic welding improves welding position accuracy, welding consistency and production efficiency. It supports programmable welding paths for different cylindrical battery pack layouts.

Selection Notes

5000A or 8000A inverter DC power supply can be selected according to nickel strip thickness, cell type and battery pack structure. Welding fixture, welding path and welding needle design should be confirmed together with the pack drawing.

Information Needed for Quotation

• Cell model and battery pack layout
• Nickel strip material and thickness
• Single-side, double-side or conveyor welding requirement
• Required production capacity per hour
• Battery pack drawing or sample photos
• Required power supply, such as 5000A or 8000A inverter DC

FAQ

Can this machine weld different cylindrical cell packs?

Yes. The welding program and fixture can be configured according to the battery pack layout, cell model and nickel strip design.

What is the benefit of automatic spot welding?

Automatic spot welding improves welding position consistency and reduces manual operation difference, especially for repeated battery pack models.

When should I choose double-side or conveyor type?

Double-side welding is suitable when both positive and negative sides need efficient welding. Conveyor type is more suitable for continuous production and line connection.
