摘要: 研制了一种新型的四柱式焊缝自动跟踪用涡流传感器.传感器激励线圈在工件中感应出涡电流,利用测量线圈检测涡流的大小以获得焊缝位置信息,可以检测出薄板对接焊缝横向和纵向位置信息.它具有非接触、尺寸小、灵敏度高、响应速度快、并可以用于非铁磁性材料的特点,已成功地应用于焊接自动跟踪系统.对其原理、传感器探头、信号处理方法、传感器特性等进行了详细的介绍.

Abstract: A four-test-winding eddy current sensor for seam tracking was introduced to improve the accuracy of automatic seam tracking system for sheet butt joint. Both horizontal and vertical deviation information can be gained from testing the eddy current induced by the excitation winding. In addition to advantages such as non-touch with work pieces, high sensitivity and rapid response , the sensor is also suitable for non-magnetic material. An automatic seam tracking system based on the eddy current sensor has been developed. The principle ,processing circuit and experiment results of the system were presented in detail.
