焊管纵向焊缝实时跟踪系统的研究

提出了一种弧形滑架的焊缝实时跟踪系统，对其工作原理、主体结构、控制系统的软件设计等要点进行了阐述。该系统采用激光传感器测量焊缝的位置，并采用一种带修正函数的控制规则自调整模糊控制进行焊缝的纠偏。采用DSP作为核心控制器产生控制信号，驱动焊枪沿高度方向运动并沿弧形导轨转动，实现焊枪对焊缝的实时自动跟踪。生产中的使用结果表明:该系统可以实现焊枪对焊缝的实时自动跟踪，完全满足连续焊管生产线的需要。

Research on the Real-time Longitudinal Weld Tracking System of Welded Pipes

A real-time weld tracking system of arc slide was presented in this paper. The working principle, the major structure，and the software design of control system were described . The laser sensor is used in this system to measure the position of the weld, and the fuzzy controller with self-adjusting function is adopted to rectify deviation of the weld. DSP is used as the central controller to produce control signal, which drives to move along weight direction and arc slide, in order to realize real-time weld tracking .The actual application results showed that the system can realize real-time automatic weld tracking of the welding torch，which can meet the requirement of the continuous welded pipe production line.
