ERW (Electric Resistance Welding) needs to go through a series of processes from raw materials to finished products. The production process flow mainly depends on the product variety. The completion of these processes requires various mechanical equipment and welding, electrical control, and testing devices. These equipment and devices follow different process flows. A variety of reasonable arrangements are required.
