SPOT WELDING NIDDLE COPPER

The Spot Welding Needle (Copper) is a precision electrode tip used in battery spot welding machines for joining nickel strips to lithium-ion battery cells. It is made from high-conductivity copper to ensure efficient current transfer and strong, consistent welds.

This component is widely used in EV battery pack manufacturing, lithium battery assembly, and industrial welding applications, where accurate and stable spot welding is required.

## Key Features

• Made from high-purity copper (excellent conductivity)
• High resistance to heat and welding stress
• Provides stable and consistent welding current transfer
• Precision-machined tip for accurate spot welding
• Good wear resistance for repeated industrial use
• Easy to install and replace in welding machines
• Available in different shapes (pointed, flat, rounded)

## Applications

### Lithium Battery Manufacturing

Used for welding nickel strips to 18650, 21700, 26650, and prismatic cells.

### EV Battery Pack Assembly
