Provided is an end wall of a railway wagon made by aluminum alloy and a manufacturing method thereof utilizing friction stir welding. The overall end wall is formed by splicing of aluminum alloy sections. According to the shape and the requirement for the end wall of a wagon body, the aluminum alloy sections are welded by friction stir welding in order to form the overall block of the end wall made by aluminum alloy.The friction stir welding is realized by arraying the aluminum alloy sections forming the end wall of a railway hopper wagon according to the sequence. All the aluminum alloy sections are welded for connection by means of friction stir welding. Therefore, the overall end wall of the railway hopper wagon is formed. The end wall of the railway wagon made by aluminum alloy and the manufacturing method thereof utilizing friction stir welding have following beneficial effects: a wall plate is formed by the aluminum alloy sections and is featured by being stable in structure, high in strength and attractive in external appearance; compared with a conventional mode that plates are utilized for being riveted onto a framework, the overall strength is improved a lot; and the appearance looks attractive.
