The steel structure has the characteristics of industrial production of components, good anti-seismic performance, low manufacturing cost, recoverability and the like. Among them, steel pipes (including square pipes and round pipes) are one of the most commonly used steel members. In practical application, due to the requirement of structural stress, transverse stiffening baffles are often required to be arranged in steel pipes, and full penetration welding seams, such as box columns (generally square tubes) for steel structure frame buildings, are required to be adopted, and full penetration welding transverse inner baffles are required to be arranged at the joint of the box columns and the steel beams. However, due to the limitation of the cross-sectional size of the common steel pipe, a welder cannot enter the steel pipe to weld, so that a very complex process of cutting steel plates for assembling and welding the box column is required, and the welding of the inner partition plate is completed in the complex process, thereby being labor-consuming and time-consuming and increasing the cost.
