Laser Welds
WARNING: This page is about a different car, the 2025 Volkswagen Jetta. However, it is still accessible from the selected car via links, so may be relevant.
The roof and body on this vehicle are partially laser-welded.
When laser welding, a high energy light beam is directed onto the weld points via optical lenses or fiber optics.
During the welding process, the upper panel is melted through and the lower panel is melted on the surface, thereby forming a weld without using any additional materials.
When repairing (except roof repairs), laser weld seams are replaced by gas-shielded arc continuous weld seams or straight-line spot weld seams.
