The Welding Tightrope: Balancing Speed and Reliability
Ever wondered why some battery packs fail prematurely? The devil's often in the welding details. Here's what separates the pros from the amateurs:
3 Critical Welding Factors
- Heat Control: Keep temps between 200-300°C to avoid lithium degradation
- Joint Design: Lap joints vs. tab welding – which suits your application?
- Material Prep: 0.1mm surface roughness max for optimal bonding
| Method | Speed | Defect Rate | Cost per Unit |
|---|---|---|---|
| Laser Welding | 15 cells/min | 0.3% | $0.18 |
| Ultrasonic | 22 cells/min | 1.2% | $0.12 |
