| Abstract: | Investigation on seam auto-tracking is very significant to improve the welding quality and efficiency. In this study, welding seam automatic tracking executive system is developed based on CCD visual sensor and programmable logical controller （PLC）. Executive mechanism of auto-tracking system is developed according to the function of realization. Moreover the electric circuit of PLC and longitudinal and transverse motors are designed also. This paper introduces the communicate programs between PLC and the upper computer. This system adopts proper PID parameters and meets the demand of welding seam auto - tracking. |
