1000W Laser Welding Machine For Lithium-Ion Batteries Welding

1.Equipment Introduction

It is a special model designed and developed for the welding of lithium-ion batteries (communication power battery, power storage, etc.). After equipped with appropriate fixtures, the series system can complete laser welding of square battery shell cover (four straight edges and four arc angles at the joint of shell and cover plate).

2. Workflow

Manual Feeding → Cylinder Pressing → Press the Start Button and Wait for Welding → Cylinder Loosening after Welding → Manual Feeding and Cyclic Operation.
