[0002] Metal doors, as the name suggests, refer to doors mainly made of metal materials (such as aluminum alloy, stainless steel, copper, etc.). They are widely used in various occasions such as residential, commercial buildings, public facilities, etc. due to their durability, beauty and high safety.

[0003] When processing metal doors, each component needs to be welded and fixed. During welding, welding work needs to be performed on both sides of the splicing position. Generally, after welding on one side is completed, the door panel is manually flipped over, and then welding work is performed on the other side. Such manual flipping is not automated enough, which reduces the processing efficiency of the metal door, and manual flipping is more laborious. At the same time, welding will produce a large amount of harmful gases. If directly discharged, it will be inhaled by surrounding operators, affecting the health of the operators.
