| Abstract: | With the development of aluminum alloys, progress has been made in railcar body structure and welding techniques. The paper presents the transition from traditional single shell car body structure composed of external plate and frame to complete external shell car body consisting of hollow aluminum extrusions, and the evolution of welding techniques from MIG spot welding to friction stir welding (FSW). |
