Abstract
A production line and a method for welding the automobile rear floor panels are provided. In view of the current problem that the position of the wheel housing of the rear floor workpiece affected by the reinforcement structure is not convenient to weld directly, the rounded rectangle workpiece conveying path is adopted. When the direction is adjusted during the workpiece conveying process, the posture relative to the previous station also changes. The welding mechanism of the previous station or the welding mechanism of the next station is used to weld the wheel housing position of the workpiece and weld from the lower part of the wheel housing upward. The molten pool and welding slag after welding are not easy to attach to the workpiece under the action of gravity to cause defects, and can reduce interference with the workpiece structure, and improve the welding efficiency.
