OCT for Laser Welding

The optical coherence tomography (OCT), an optical measuring process, is especially suitable for a combination with scanner based laser welding processes. OCT monitoring permits a precise and highly dynamic gain of information in all process zones and therefore it creates the basis for an optimal process progress with continuously optimal results.

Pre-Process OCT
Welding Seam Tracking
  • Tracking of the joint edge in advance to the active welding process
  • Early identification of cracks
  • Avoidance of connection errors
  • Direction depending seam tracking
  • Ideal for fillet welds
  • Maximum flexibility due to large scan field
In-Process OCT
Keyhole Depth Monitoring
  • Innovative measuring process
  • Checking the achieved welding depth in situ
  • Continuous monitoring of the welding process
  • Recording of process fluctuations 
  • Proven measuring methodology
     
Post-Process OCT
Welding Seam Inspection
  • Online visualization of the welding seam
  • Automatic identification of seam errors
  • 100% documentation of the results
  • Evaluation on the basis of pre-defined factors
