This very popular document has just been updated to version 4.0, and is now available. The Laser Plastic Welding Design Guidelines is a powerful document for engineers designing applications for laser plastic welding. This improved document covers the main factors affecting a quality weld, material considerations, process types, and much more.
This chart displays the most common, weldable thermoplastics. Each sample of this study was done with the plastic materials in their natural state. Please take note of the color system which indicates weld quality.
For more information on plastics a compatibility please see the Laser Plastic Welding Design Guidelines document or the Design Guidelines webinar.
Solid knowledge and execution of clamping and fixturing can have a profound effect on the laser welding process. To ensure quality welds during laser plastic welding, intimate contact between the two parts is paramount. Close contact will allow for adequate heat to be transferred, through heat conduction, from the absorbing lower layer to the transmissive upper layer.
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.
