[0004] Regarding the above-mentioned related technologies, when using the aforementioned equipment to assist in the welding of the hinge ears of civil defense doors, it was found that there were problems with the welding quality of the hinge ears. After many experiments, it was found that this was because during welding, a certain angle needed to be maintained between the hinge ear and the welding gun according to the thickness of the hinge ear, and the hinge ear itself also needed to maintain a certain inclination angle to ensure that the molten solder at the weld can flow under the action of gravity during welding.
