Abstract

The primary focus of this paper will be upon the application of Robotic Laser Welding on automotive sheet metal components, sub-assemblies and the complete body itself. Also reviewed is the world’s first production on-line application of Robotic Laser Welding of the roof panel to quarter panel joint on a complete body in the U.S.A. The major subjects covered include the following: Overview of laser welding vs. resistance spotwelding; Advantages of laser welding vs. resistance spotwelding; Design flexibility of laser welded joints; Requirements for successful laser welding systems; Advancements in robotic laser systems both CO2 and Nd:YAG; Applications of in-production laser welded assemblies; and, Laser welding challenges of the future.
