Abstract

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.

Description

technical field [0001] The invention relates to a component of a railway freight car and a manufacturing method thereof, in particular to a railway freight car end wall and a welding manufacturing method thereof, in particular to a method and a product for making a railway aluminum alloy freight car end wall by friction stir welding, The invention belongs to the technical field of railway wagon manufacturing. Background technique: [0002] Railway cargo transportation is an important part of railway transportation, and the vehicles used to carry goods on the railway are collectively called railway wagons. According to their different purposes, they can be divided into general-purpose trucks and special-purpose trucks. The main types are box car, gondola car, tank car, flat car and hopper car etc. Recently, in order to improve the transportation capacity, it has been proposed to use aluminum alloy materials to make railway wagons, among which the aluminum alloy railway hop...
