Laser welding

The area below the drip rail is laser welded.

With laser welding a light beam of high energy is guided over the weld via optical lenses or fibre optics.

During the welding process the upper panel is melted onto the partially molten lower panel creating a weld joint without the need of additional material.

During collision repair the laser weld seam is replaced by an SG-plug weld seam.
