摘要
介绍以弧压为传感信号的摆动式TIG焊焊缝跟踪技术。硬件设计方面,采用两级滤波的方法,前级主要用来保护控制电路,后级主要用来滤除杂波。软件处理方面,针对搭接TIG焊的特点,采用摆动焊接方法,利用积分比较法,实现了焊缝的自动跟踪;提出加权处理的方法,对积分比较法进行修正,进一步保证了跟踪的实现,提高了跟踪精度。试验证明,该技术控制可靠,焊缝跟踪效果好。
This paper introduces the seam tracking technology in arc-swing type TIG welding,which takes the arc voltage as sensor signal.For hardware designing,it adopted the method of twice filtering.The primary is mainly used to protect the control circuit,and the secondary is used for filtering.For software,it takes use of the swing torch and integral contrast method to realize the seam auto tracking according to the characteristics of lap joint TIG welding;It points out the method of weighted handling to proceed a revising to the integral contrast,which ensures the tracking properly and improves the tracking accuracy.The experiments prove that the technology is reliable and the seam tracking works well.
