超声传感埋弧焊焊缝跟踪的研究

本文提出了一种非接触超声传感埋弧焊焊缝跟踪系统。介绍了超声波传感器及其焊缝跟踪工作原理。在焊缝跟踪中既可以采取检测焊缝坡口的跟踪方法，也可以采取检测磁性胶条的跟踪方法。埋弧焊焊缝跟踪实验表明，该系统具有良好的动态性能和控制精度。该焊缝跟踪方法能够满足压力容器焊接工程的需要。

Study on the Seam Tracking with Ultrasonic Sensor in SAW

A new kind of the seam tracking system with non-contact ultrasonic sensor in SAW is presented in this paper.The ultrasonic sensor and the wo rking principle in the seam tracking are explained.In the seam tracking,the meth od of checking the weld groove is used,but also the method of checking the magne tic rubble belt is adopted.The results of the SAW seam tracking experiments show that there are good dynamic characteristics and control accuracy in the system. This method of the seam tracking can satisfy the requirements of the pressure v essel winding engineering application.
