Design Guidelines: Hybrid Laser Welding of Automotive Lighting

This design guide is an elaboration on the original LPKF Design Guidelines for Laser Plastic Welding. You will find this document has a specific focus on automotive exterior lighting. All of the considerations have been adapted to this topic and other details have been added.

The purpose of this Automotive Lighting design guide is to help engineers understand the process and the type of considerations required to implement laser hybrid welding in auto lamp assemblies.

Laser hybrid welding of automotive lighting is a promising technology offering many advantages over traditional welding methods (hot-plate, vibration, ultrasonic, etc.) including: simple joint designs, the ability to handle large and complex shapes and the elimination of the post-weld annealing process.
