The OCT system from Lessmüller Lasertechnik, which is based on optical coherence tomography, offers the unique possibility of measuring the depth of the keyhole and thus the weld penetration depth during the welding process. The OCT measuring beam is collinearly coupled into the processing beam and directed to the deepest point of the keyhole. No other method succeeds in detecting the weld penetration depth in such an economical way.

Monitoring the weld penetration depth provides crucial insight into the stability of the finished weld and the stability of your process.

The nature of the keyhole varies and depends on the process parameters and the materials used. Proven algorithms adapt the OCT measurement to the respective conditions and ensure reliable weld penetration depth measurement.

All measurement and evaluation data of the OCT system from Lessmüller Lasertechnik can be stored in each case and thus enable complete traceability.

Lessmüller Lasertechnik also offers to examine your process for the possibility of welding depth measurement in our in-house laboratory. Please contact us.
