Zusammenfassung:	Provided is a sidewall plate of a railway hopper wagon made by aluminum alloy and a friction-stir welding method thereof. The sidewall plate is integrally formed by splicing of aluminum alloy sections. According to the shape and the requirement for the sidewall plate of a wagon body, different aluminum alloy sections are adopted and welded together by friction-stir welding in order to form the overall sidewall plate made by aluminum alloy.The friction-stir welding is realized by arraying the aluminum alloy sections forming the sidewall plate of the 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 sidewall plate of the railway hopper wagon is formed.The aluminum alloy sections are adopted for forming the wall plate featuring a stable structure, high strength and attractive external appearance. Compared with the mode that plates are utilized for being riveted onto a framework, the overall strength is improved a lot; and the appearance looks attractive.
