Laser Welding Machine For Lithium-Ion Prismatic Battery Welding

1、 Equipment Overview

A specialized model designed and developed for the welding of lithium-ion batteries (communication power batteries, energy storage, etc.). With proper clamps, this series of systems can complete the laser welding of aluminum sheets for the liquid injection holes of the prismatic cell case cover and the positive and negative electrode welding of the collector plates of the cover plate.
