[0002] With the continuous development of industrial manufacturing, the demand for manufacturing large equipment is increasing, which involves the welding of large cylinder sections. The main function of cylinder section longitudinal seam welding is to connect two or more cylinder sections into a whole to achieve the requirements of structural integrity and strength. In the manufacturing process of large equipment or components, cylinder section welding is a key link, because the cylinder section is large in size and heavy in weight, and it is difficult to fix it through conventional connection methods. Through longitudinal seam welding, multiple cylinder sections can be effectively connected together to form a stable and reliable equipment or component. This helps to improve the overall strength, stability and service life of the equipment.

[0003] Traditional welding methods mainly focus on improving welding quality and efficiency, while ignoring the stability of the structure during welding. Although there are some welding auxiliary equipment or methods, large cylinder sections are difficult to fix through conventional connection methods during welding due to their large size and heavy weight. They often face the risk of structural instability or even collapse, and there is no special design to prevent large cylinder sections from collapsing. This problem not only affects production efficiency, but more importantly, it will bring serious safety hazards to on-site workers. Utility Model Content
