Automatic Spot Welding Machine with Rotary Head for Battery Pack

Automatic Spot Welding Machine with Rotary Head for Battery Pack

The AOAO-960XZ Single-Sided Automatic Spot Welding Machine is a high-efficiency battery pack assembly system designed for cylindrical cell welding applications. The machine integrates automatic welding, multi-axis servo motion control, and a rotary welding head, enabling precise and consistent welding of nickel tabs across various battery configurations.

This system is specifically engineered to handle pure nickel strips with thickness ranging from 0.1 mm to 0.3 mm, ensuring strong weld quality and stable electrical performance. With its programmable control system and high-speed welding capability, the machine is suitable for both small-batch production and large-scale battery pack manufacturing.

Core Advantages

Automatic Welding System

● The machine operates with a fully automated welding process, significantly improving production efficiency while reducing operator dependency. Welding parameters can be precisely controlled and stored for repeatable production.

Rotary Welding Head Design

● The integrated rotary welding head supports angle adjustment within ±45°, allowing flexible welding positions for complex battery pack structures and improving accessibility in multi-row configurations.

Pure Nickel Welding Capability (0.1–0.3 mm)

Optimized for battery manufacturing, the system supports:
● 0.1–0.2 mm pure nickel strip direct welding
● 0.21–0.3 mm nickel strip (slotting or projection required)
● Copper-nickel alloy welding with structured slot design
● This ensures compatibility with a wide range of battery pack designs.
