Today’s methods for the inspection of the position of weld seams in glass, which has a decisive effect on the strength and thus on the
quality of the permanent bond, are costly and often carried out manually in a destructive manner. The present paper proposes the application
of optical coherence tomography to determine the position of the weld seam by evaluation of the signals caused by the voids within
weld seams. Blind welds of fused silica and alkali-aluminosilicate glass were investigated, and a method for data evaluation is presented. The
method is predominantly suitable for glass that exhibits the formation of distinct voids during welding and provides an approach for online
monitoring and control of glass welding processes.
