The invention relates to a flexible production work station for an automotive welding production line, which is characterized in that: a middle position of the work station is provided with a working position of a frame sliding table, a middle position of the frame sliding table, and a switching position of the frame sliding table, and the three positions are driven by a motor. Two transverse sides of the switching position of the frame sliding table are provided with an automobile type clamp switching position respectively. Three to six automobile type clamp positions can be arranged in front and behind the automobile type clamp switching positions on two sides. An automotive body-in-white welding clamp is arranged in front of the working position of the frame sliding table. The flexible production work station for the automotive welding production line can meet the requirement on flexible welding production of multiple automobile types, realize fast switching work between multiple automobile types in short time, improve the welding quality, reduce the labor strength of workers, and improve the work environment.
