Capillary depth monitoring and seam geometry measurement – Busbar 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.
