How This Spot Welding Machine Works
Step 1: Cell and Tab Preparation
First, you prepare the cylinder cell case and the nickel tab to be welded. The tab is positioned at the bottom of the case where the negative terminal connection will be made.
Step 2: Needle Insertion
The 2mm diameter × 180mm welding needle is inserted into the cylinder case, reaching down to the bottom where the nickel tab is positioned.
Step 3: Parameter Adjustment
You adjust the welding parameters based on your specific materials:
- Welding current: 0-99A – set according to tab thickness
- Pressure: Independently adjusted on the welding needle
- Pulse mode: Select monopulse, dipulse, or multiple-pulse via microcontroller
Step 4: Welding Operation
When activated, the pneumatic system applies controlled pressure through the needle. The microcontroller delivers precise welding current pulses, creating a clean, strong weld between the nickel tab and the case bottom.
Step 5: Quality Result
The result is a beautiful weld spot with no sparks, stable current, and a reliable electrical connection essential for battery performance.
