영문 초록

In modern industry, carriage or keeping of distribution using transportation such as aircraft, sail, train, vehicle etc, is a common method. In this fierce manufacture site, to build storing facility which is lighter, longer, stronger and safer to carry is the way to economize transport cost. Container is being used most for distribution transport in industrial site. For that, we investigated how to produce containers faster without flaws, which material to choose, what proper welding method and speed are, and which welding wire or protective gas is good for keeping long span. Also examined, how hardness, chemical components and fatigue strength of material change, as welding was proceeded. Through assay of hardness, chemical analysis, and fatigue strength, identified how outer fault of welded part caused welding speed occurs. By attaining flawless welding conditions, this study will help for mass production of containers.
