Abstract

The measurement of depth of a laser capillary in industrial conditions by Optical Coherence Tomography technique is demonstrated in this work. This paper highlights the results achieved by the recent combination of ultrasound sensitive membrane-free optical microphone by XARION and PRECITEC’s OCT IDM system. Joint interpretation of the ultrasound spectrograms and the digging curves of the keyholes enables better understanding of the dynamics of the melted metal and determination of the ideal welding parameters.
