The design of the seam tracking sensor is the key work in the realization of the welding automatization. A novel touch photoelectric sensor for seam tracking was designed on the base of getting over the shortcoming of non-touch seam tracking sensor and using the principle of the photovoltaic translation. The idler pulley can touch the seam closely, then the sensor can realize the auto-tracking by the oriented function of the groove. If the offset of the idler pulley location appear, the sensor can change the offset to the voltage using the cell of the photovoltaic translation and the cell of signal processing.
