[0002] Prefabricated box girders are common facilities in construction projects. They are mainly made of concrete and steel cages. The production process of the steel cages used to make prefabricated box girders is directly related to the production quality and efficiency of the prefabricated box girders. When processing the steel cages at the construction site, most of them are welded and formed using a roll welding machine.
