Problems solved by technology

[0002] With the rapid development of cities in our country, more and more super high-rise buildings have appeared in cities. The most common structural form of super high-rise buildings is the combination of core tube and steel structure. The outer steel structure has various forms. Filling the steel pipe column with concrete is a relatively common type. The butt joint of the steel pipe column requires full penetration welding for the first-class weld. In order to ensure the welding quality, the liner will be welded at the joint of the steel pipe for the butt full penetration welding. At this time, it is necessary to closely fit the welding backing flat steel to the inner wall of the steel pipe for welding. Manual operation is not only inefficient, but also difficult to fit the welding backing flat steel to the inner wall of the steel pipe, which seriously affects the welding quality.
