摘　　要：针对电阻焊焊管生产过程中,焊缝位置保持不变会对圆管尺寸和轧辊寿命产生不良影响的问题,从确保焊管尺寸公差、延长轧辊使用寿命和满足异型管使用要求等方面,分析了焊缝位置调控的必要性。提出了调整焊缝位置的方法,如成型辊法、导向辊法和定径辊错位法,并介绍了这些方法控制焊缝位置的基本原理及其控制效果和优缺点。在实际生产过程中,可以结合实际情况单独使用或组合使用这些调整方法以达到更好地调整效果。During ERW pipe production process, the unchanged weld position has a harmful effect on pipe size and roll life. In this article, it analyzed the necessity of weld position adjusting from several aspects, such as to ensure welded pipe size tolerance, prolong service life of roll, meet operating requirements of special pipe and so on. It put forward the methods of adjusting weld position, including forming roll, guide roll and sizing roll displacement method, it also introduced the fundamental principles of these control methods, as well as control effect, advantages and disadvantages. In the process of practical production, these adjustment methods can alone or in combination be used combined with actual situation, in order to achieve better adjustment effect.
