In this article, it introduced the development history and characteristics of SAWH pipe tack and finish welding process, and compared its advancement with the traditional one-step manufacturing process. It emphasized 3 kinds of different finish welding stations, such as frame construction method, spiral driving method and welding cart method. It respectively summarized the advantage and disadvantage of the above three methods and its application condition, and pointed out the main difference lies in the different transfer system, which will greatly affect manufacturing costs and running accuracy. Finally, it put forward the opinions and suggestions of popularizing of the tack and finish welding process of SAWH pipe by adopting different methods in finish welding station.%介绍了螺旋埋弧焊管预精焊生产工艺的发展过程和特点,以及与传统的一步法制造工艺相比具有的先进性.重点介绍了门式框架结构方式、螺旋传动方式以及焊接车方式这3种不同的精焊工作站形式,并对其各自的优缺点和当前的应用状况进行了论述.指出3种方式主要区别在于钢管的传送系统不同,这对其制造成本和运行精度有较大的影响.最后,提出了利用精焊工作站不同方式推广螺旋埋弧焊管预精焊生产工艺的看法和建议.
