Precitec IDM

Determination of the penetration depth


Determination of the penetration depth

The In-process Depth Meter IDM can be used to perform distance measurements even when processing with high power lasers. The seam depth is a significant and critical seam property value in laser beam welding. The Precitec IDM system determines the penetration depth in the deep welding processes at all metal-to-metal joints.

The integration of the Precitec IDM in new or existing LWM process monitoring systems allows to detect process irregularities without relating them to physical measures and permits the comparison with the set thresholds. Smallest deviations inside the vapor capillary can now be used for component evaluation. Due to the simultaneous distance measuring to the workpiece surface TwinTec distance changes during processing do not distort the measurement result. Only its absolute depth is used for the quality assessment of a workpiece.

The process emission has no influence on the measuring accuracy. Powertrain or laser welding of body panels are application examples.
