Box Beam Welding Production Line, This production line is proceeding from technological point, such as lay-off cutting, manufacturing groove, assembling clapboard inside, box assembly, electro-slag welding, box welding, manufacturing edge face, shot blasting and so forth. Equipped with the main processing equipment, at the same time box-beam is always big and heavy, so we must add the conveyor of roller and chain running-over equipment to realize the part of automatic operation in the process of technological production.
