Colour sensors for automatic detection of weld spots

Brass strips are joined based on the spot welding method. CFO colour sensors are used to automatically recognise the weld spots prior to further processing. The multi-teach function allows for the colour shades of the shiny weld spots to be taught-in to colour groups. When the sensor recognises a weld spot, an output signal is output to the control system in order to initiate further processing. High measuring rates also allow for fast moving strips to be detected reliably.
