| 摘要: |
| 本文介绍了一个能够识别并能够抑制点固焊道干扰的焊缝自动跟踪系统.这个控制系统是采用扫描跟踪的方式,以传感器越过对缝时产生的过零脉冲信号为中心进行扫描,所以它的优点是当传感器开始进入点固焊道时,传感器的中心能准确地对准对接接头的中心线。 |

| Abstract: |
| In this paper,an automatic seam tracking system capable of distinguishing and tliminating the interference of tack weld is introduced.The advantage of this system is ehat the center of the sensor is just located at the center of the butt joint when the sensor enters the tack weld region.The scanning seam tracking takes the zero passing pulse as the center. |
