摘　　要：以空心轴电机直接驱动的高速旋转电弧传感器是焊接应用中使用的一种传感器,国内外将它应用于焊缝跟踪系统中,并进行了大量的研究。介绍了该传感器的结构与工作原理,阐述了采用特征谐波检测法识别焊缝偏差信号的方法。利用该方法对V形坡口进行了金属熔化极气体保护电弧焊(MIG)的跟踪试验,试验结果验证了所用方法的有效性。The high speed rotating arc welding sensor drived by motor with hollow shaft is used in seam tracking system. It is used in seam tracking system and studied both at home and abroad. The structure and working theory of the arc sensor are introduced. The method of identifying signals of the seam deviation by the characteristic harmonic detection method is expounded. Tracking experiment of MIG on V shape welding groove is made with this method, and the experiment result validates the validity of this method.
