FSO

The FSO is designed for front-side laser welding of extremely short flanges at high processing speeds with maximum strength. This saves material and reduces the weight of the welded product. At the same time, the process gives users a high degree of design freedom.

Function description

Optical seam tracking, clamping technology and positioning scanners are fully integrated into the FSO processing optics. The seam tracking works with the positioning scanner to ensure precise positioning of the laser beam between the front sides of two sheets. This compensates for positioning and manufacturing tolerances as well as for deviations in the ideal robot path when creating the edge seam. The FSO can also be used to join multiple sheets in a single process step.
