Abstract
Study of the arc sensor to had turning to detection accuracy,in this study,As we look to the reliability of the various disturbances,and develop arc sensor to incorporate the theoretical formula of welding phenomena.Use in direct-type four-axis robot,and performs welding by generating arc actually to program control.Experimental results arc length was found that the variation of the voltage becomes larger and longer.lt was possible to make uniform the dispersion of the arc voltage by applying the filter.Graph of simulation graphs and measurement experiments he want you to match,but I understood that the voltage is high graph came out in the experiment,the voltage difference between the end and the center is large.Seems robot has a high position when a welding voltage higher than the experimental expression is measured.More accurate values issued by applying a filter in the graph of the approximation curve.
