OCT (Optical Coherence Tomography)is an optical measuring principle widely used in the field of ophthalmology.

OCT-applications:

Seam tracking of fillet welds

Seam tracking of overlap welds with reference edge

Seam inspection of any weld

Laser welding of seat components is one of the biggest markets for remote laser welding. 

Possible OCT applications:

Seam tracking is asked for reverse flange welds and other geometries

Online seam inspection is a big advantage
