VisionLine OCT Check

Welding depth monitoring and seam geometry measurement

Process-synchronous quality control in welding

The VisionLine OCT Check process sensor system ensures reliable and precise welding depth monitoring. The use of optical coherence tomography (OCT) makes process-synchronous quality assurance possible, for example by measuring the keyhole depth in deep welding processes. The geometry of the solidified weld seam is measured by an additional OCT scan. Due to the optimal interaction of PFO and OCT, process-synchronous measurement of keyhole depth is possible in the entire work area of the PFO - with no parameter adjustment necessary.

Robust

The robust OCT design and clever integration into the optics system enable measurements even under fluctuating ambient conditions.

Fully integrated

For minimal interfaces and simple integration of systems

Easy operation

User-friendly software interface

Fast

Fast availability of results for and low cycle times

Transparent and traceable

Inspection of each component with 100% traceability of the welding depth along the entire weld seam

Including VisionLine OCT Detect

All VisionLine Detect and VisionLine OCT Detect features are already included.
