Principles of Laser Welding and Its Application in Battery Welding
Laser welding is a precise and efficient technique widely employed in diverse industries such as electronics, automotive, and aerospace. Its significance is particularly notable in battery manufacturing, where it plays a crucial role in assembling battery cells and packs. This article aims to explore the principles of laser welding and examine its applications in welding battery components. Principles of Laser Welding Laser welding utilizes the concentrated energy of a high-powered laser beam to fuse materials together. The fundamental principles of laser welding are outlined below: 1. Laser Generation: Laser light is generated through stimulated emission, where photons are produced within a laser cavity, often using a medium such as a crystal or gas. These photons are then amplified and emitted as a coherent and monochromatic beam of light. 2. Focusing: The laser beam is directed and concentrated onto the welding point through a system of mirrors...
