预精焊螺旋焊管精焊机组焊缝跟踪方式研究

Study on Weld Tracking Mode of Finish Welding Unit in SAWH Pipe Two-step Welding Process

两步法预精焊生产是螺旋埋弧焊管生产的一个重要发展方向,而焊缝自动跟踪是精焊机组自动控制系统的一个重要组成部分。通过对跟踪系统跟踪原理的分析与焊缝跟踪驱动方式的介绍,说明了精焊机组焊缝跟踪的实现原理。最后,介绍了一种内焊跟踪外置的跟踪方式,并对其优缺点进行了简单的分析。

Two-step welding process is an important development direction for SAWH pipe production, and weld automatic tracking is an important part of finish welding automatic control system. In this article, it analyzed the working principle of weld automatic tracking system, introduced the drive mode of weld tracking system, and explained the implement principle of finish welding unit weld tracking. Finally, it introduced a kind of inside weld tracking system, which was installed outside steel pipe, and briefly introduced the advantages and disadvantages of the above tracking system.
