Laser Welding Applied to Rear Body Structure

We studied possible applications where advantages of laser welding can be best utilized. As a result, we have found that we can obtain a weight-reduction effect around the room partition, upper back panel. We constrained the outside periphery of the partition panel, which contributes much to the tortional rigidity of the body, with continual laser welding. Thus making it possible to obtain the target torsional rigidity with a lightweight body thanks to the synergetic effect of optimized V-beads and simplified structures of peripheral parts.
