During use, it is found that the column is a single long column, and due to the non-adjustable length during transportation, it is not convenient for transfer transportation. Moreover, when the submerged arc automatic welding machine rotates on the column through a sliding sleeve during the welding process, due to the action of the chain hoist torque, it automatically rebounds after rotating a certain angle and cannot truly achieve 360° dead-angle-free welding.
