According to the welding tool for the airflow plate and the hook of the turbojet engine, the base is adopted to support the airflow plate, the locking screw is arranged on the base, the welding position of the airflow plate is fixed above the airflow plate through the pressing plate and the locking nut (the locking nut is matched with the locking screw, and the airflow plate can be fixed by rotating the locking nut, so that the airflow plate can be fixed. The locking nut is arranged on the pressing plate, so that the locking nut applies downward pressure to the pressing plate, and then the pressing plate presses the airflow plate below, so that when the airflow plate is subjected to hook welding, the airflow plate is pressed by the pressing plate, deformation such as edge curling is not prone to occurring, and then it is guaranteed that after the hook welding procedure of the airflow plate is completed, the appearance size of the airflow plate is basically kept unchanged.
