[0002] Box beam refers to a large box beam made of steel, which is mainly used in roof structures of industrial and civil buildings, crane beams, bridges and hydraulic gates, etc.
[0003] In the preparation process of existing box beams, submerged arc welding is usually used for welding between each section. The web and wing plates of the box beam need to be welded at the submerged arc welding station of the welding production line. During the welding process, due to the influence of welding stress, the wing plates on both sides will be deformed and the wing plates will be arc-shaped. Due to the limit fixation of the web plate in the middle, the two sides of the wing plates are inclined inward.
[0004] Usually, to solve this problem, the wing plate is heated after welding, and then leveled and corrected to restore the wing plate to a flat state, but this method is too time-consuming and labor-intensive, and the effect is not good. Utility Model Content
