摘要： An apparatus for regulating the welding deformation of a box-shaped structure, said apparatus comprising: a supporting part and a regulating part; a supporting surface that supports a box to be welded is formed on the supporting part; the regulating part is connected to the supporting part and at least abuts against a welding surface of said box; during the welding process, the regulating part regulates the flatness of said box by means of regulating the magnitude and/or force application position of a force acting on the welding surface of said box. In the regulation apparatus, multi-point flexible support is arranged on a bolster box-shaped structure, so as to achieve real-time dynamic regulation and step-by-step precision regulation, thereby improving the manufacturing precision of a bolster, and eliminating post-welding modification and repair of the bolster box-shaped structure. Also disclosed is a method for regulating the welding deformation of a box-shaped structure.
