A modern non-optical.

A modern non-optical, noncontact seam-tracking sensor checks disclosed welds in manufacturing environments where vapor dust, debris, and oils are for the use of all The ST45, from SenSolve Inc., Albuquerque, uses fringing electric-field sensing technology to track part features during robotic-arc welding. SenSolve freshly integrated its ST45 robotic seam-tracking sensors with the Motoman MRC series controller

During robotic welding, ST45 sensors measure torch cross-seam position, height, and work angle in real-time and throw corrections to the MRC controller The welding-torch position
