Development of Production Technology for Aluminum Rolling Stocks

알루미늄 철도차량의 생산 기술 개발

Production technologies for aluminum rolling stocks are mainly related to welding of aluminum alloys. Automatic welding of extrusion profiles and control of welding deformations are the important contents of the production technologies. Another production technology other than welding is the technique for surface treatment of aluminum carbody. In this paper, problems caused during construction of the test carbody are described and the remedies for the problems are suggested. The accumulated experiences and systematic data will be helpful for the mass production of aluminum rolling stocks in the furture.
