Seam tracking/guidance

SEAM TRACKING/GUIDANCE

Precise seam search and seam tracking – individually adapted to your welding processes

Precise positioning of the processing laser creates the prerequisite for optimum welding results. At the same time, the use of remote processes and welding-on-the-fly in industrial series production makes a decisive contribution to avoiding unproductive repositioning phases.

Lessmüller Lasertechnik offers you various seam tracking systems that can be used in combination with laser welding optics from a wide range of manufacturers and ensure high-quality seams in efficient production. These automated and highly dynamic systems determine and control the optimal welding position while compensating for component tolerances or changes in the welding plane:

  • The OCT (Optical Coherence Tomography) system provides highly accurate, non-contact surface measurement of all common joining points as well as dynamic position correction of the processing laser beam during the welding process in real time. Hairpins can also be precisely measured with this system in terms of geometry and their position relative to each other in order to achieve the optimum welding position. In principle, OCT is compatible with all common welding optics.
  • The LSO system (Lens Shifting Optics) is an in-house processing optics for joints with small deviations of up to 2.5 mm. LSO closes the gap between fixed optics and process optics with scanner technology. Here, LSO and OCT form an ideal system unit that guarantees highly dynamic correction of the welding position and the focal position during the welding process and reliably ensures an optimum welding result. For the user and integrator, this unit presents itself as a black box that is easy to integrate.

Batteriebau

Process monitoring battery construction

Without laser welding, the implementation of electromobility on a large scale would be unthinkable! The laser is used in the construction of battery cells, in the joining of cells into modules, in the installation of modules in packages and also in the drive itself as well as in the construction of electric motors and power electronics. And no laser process without sensors! Therefore, the technology around optical coherence tomography, OCT for short, has a special role to play in this … >> read more
