A Study on the correction of production related problems in stainless steel rolling stocks

스테인레스강 차체의 제작 관련 문제 및 대책에 관한 연구

In this study. problems caused during production process of stainless steel carbody are investigated and solutions are found out. Roll forming process to make complex shape is introduced and surface crack on high strength stainless steel plate is investigated. Also, surface indentation is discussed and the effect of welding condition is clarified. Insulated tip to reduce the indentation is recommended for improvement of surface smoothness. Lastly. corrosion of welded joint is discussed and the effects of material, stress and environment are investigated.
