Welding Cycle Time Reduced

Circular Scanning Sensor permits location of box corners in a single measurement reducing welding set-up time by over 66% when compared to traditional linear vision systems.

Unlike linear sensors for seam tracking which use either a projected laser strip (stripers) or a linear scanning spot to locate seams, the Circular Scanning Sensor (CSS) from Oxford Sensor Technology Ltd, uses a rotating spot of laser light. Not only does this overcome the poor imaging quality associated with striper systems, it allows a full 3D model of the seam to be analysed and the start and end points of seams to be located in a single measurement.

Location of an internal or external box corner with a linear system would require three independent measurements, with the sensor being moved between each one. Using the CSS a corner is accurately located in a single measurement taking only a fraction of a second to complete.

The intensity of the rotating spot can be automatically varied whilst measuring to compensate for changes in material and the excellent imaging quality ensures accurate seam location even on aluminium
