Recently, the fact that welding conditions are dangerous for men and the shapes of seams are complex enforced the welding system to be automatic. In order to obtain this target, are chip Microprocessor controlled welding system is devised in this study. The tracking of seam shape is achieved by applying a differential transformer and by using a program developed. This welding system mainly consists of a sensor, the differential transformer, a servo power amplifier, a control system, and DC motors. It is verified that the developed welding system is able to track three kinds of seam shapes.
