An arc sensor system to compensate positional errors was developed on the foundation of sensor interface system to make use of the on-line shift function of industrial welding robot. The response of the arc sensor using the welding current and welding voltage as its outputs has been obtained by the analysis and experiments of the static characteristics of arc sensor. The model were used for developing a weld seam tracking result of the system is affected by the welding conditions. Thus an arc sensor system was developed by using fuzzy control approach for overcoming the difficulty of modelling.
