When industrially producing protective closed doors, the steel structure needs to be positioned, and then the positioned steel structure is welded into an integral protective closed door structure. For steel structure protective closed doors, it is usually necessary to weld the frame of the protective closed door and various connectors on the protective closed door. Since the protective closed door has high requirements for sealing, it is necessary to accurately position the structure of the protective closed door when welding the protective closed door to ensure that the door body and the door frame can be sealed.
