摘　　要：分析了柴油储罐在施工过程中,为防止焊接变形采用的控制方法。论述了罐顶、罐壁、罐底部位焊接变形的控制方案。通过调整焊接顺序、增加反变形措施和消除焊接应力的方法能够实现对柴油储罐罐顶、罐壁、罐底部位的焊接变形控制,避免发生角变形、波浪变形和凹凸变形,从而使储罐的外观质量符合国家标准的要求。This paper analyzed the control methods used for prevention of welding -caused deformation during construction of diesel oil storage tank. It discussed the control of welding-caused deformation on the tank top, tank walls, and tank bottom. By adjusting the welding sequence, adding anti-deformation measures and eliminating welding stress, the welding deformation control can be achieved on the tank top, tank walls, tank bottom, angular deformation, wavy deformation and concave convex deformation can be avoided, and thus the appearance quality of storage tank can meet the requirements of national standards.
