摘　　要：根据目前高材质、大壁厚的螺旋焊管内焊监测的现状 ,提出了用PLC、步进电机、位移传感器以及人机界面等制作一种内焊监测装置来进行内焊监测的方案 ,该内焊监测装置采用非接触式测量 ,通过计算步进电机转动的角度就可以得到钢带和内焊移动装置的纠偏量 ,从而达到对内焊控制的目的 ,系统对钢带偏移量检测精度可以达到 0 .3mm。The article put forward that to build a inside welding monitoring unit carry out inside welding monitoring scheme by using a PLC,step by step motor,shift sensor,and man-machine interface,etc.according to present actuality of inside weld monitoring for high quality,heavy wall thickness spiral submerged arc welded pipe.The inside welding monitoring unit adopt non-contact type measurement,and can obtain the correct alignment of strip and inside weld movement unit through calculating the rotation angle of step by step motor to meet the purpose of inside weld control and the system can obtain 0.3 mm inspection accuracy for strip misalignment.
