摘　　要：针对平板对接焊的错边问题,提出了一种组合电容和电感复合桥式焊缝自动跟踪方法,并设计了传感器的结构.这种复合桥式焊缝跟踪传感器利用电容对极板间距变化的灵敏检测和电感对边缘变化的灵敏检测,可以确定焊枪横向和纵向的位置关系.具有非接触、灵敏度高、抗干扰能力强、响应速度快、工作可靠的特点,并能在一定程度上克服平板对接焊的错边问题.最后,自行搭建了简单的平台进行了焊缝跟踪试验,效果良好,为焊缝自动跟踪技术提供了新的方法.According to stagger problem of problem plate butt welding, this paper proposed a method with composite bridge by combining the capacitance and inductance for weld automatic tracking,and designed the structure of sensor. With sensitive detection of the plate spacing change by capacitance and of the edge change by inductance, this composite bridge seam tracking sensor can determine the relationship between horizontal and vertical position of the welding torch. This method is of noncontact,high sensitivity,strong anti-jamming capability,fast response speed and reliable operation,and can solve the misalignment problem during plate butt welding to a certain extent. Seam tracking experiments results made on a simple platform show that the effect was good and it provided a new method for seam automatic tracking technology.
