영문 초록

This study focuses on the quality and speed of welding by using both solid wire and multi wire that applied to CO2 welding under the most suitable condition with SM390, or a hard material for welding structure, and in order to examine the mechanical characteristics, universal hardness tester and vickers tensile strength tester were used and derived from the following results. In the process of welding with a solid wire and flux cored wire, which used in CO2, Gas and Arc welding, FCAW could keep the comparatively high electricity density, and because the efficiency of its adherence, the speed of welding process can be faster. The flux cored wire of tensile load and hardness increases, and tension is almost same. CO2, Gas and Arc welding has a high mechanical hardness, thus, although it might be more expensive, because the flux cored wire is used for the essential material requiring high hardness, the increase in its quality can be expected.
