[0002] There are two structures of civil air defense door leaves, namely reinforced concrete structure and steel structure. Steel structure civil air defense doors are mainly made of channel steel, I-beams and plates. The outer frame of the door leaf is mainly composed of channel steel. I-beams of different lengths are crisscrossed to form a grid. It is mainly a combination of multiple workers to weld the channel steel, I-beams and plates. At present, in the production process of civil air defense door leaves, manual welding has unstable weld quality due to welding technology errors. The fatigue caused by long-term manual welding reduces the quality of civil air defense door leaf welding, and weld rework occurs.
