摘　　要：介绍了攀钢集团攀枝花钢钒有限公司冷轧厂2#热镀锌生产线焊机搭接量控制伺服系统的原理及特点,其搭接量可在0～6mm范围内连续可调,通过该项技术的应用,避免了焊接过程中因搭接量的变化而造成传动侧焊缝开裂、焊不上等焊接缺陷,保证了产品质量,有效提高了产品的成品率,减少了断带次数。The work principle and characteristics of servo control system for lap value of 2# CGL of Pangang were introduced. The lap value could be continuously adjusted in rage of 0- 6mm. The weld defects of weld seam cracking of drive side and without welding were eliminated which were caused by lap value changing. Therefore, the product quality could be proved.
