후판 TMCP 강재의 EGW 기법에 대한 연구

A Study on EGW Process of Thicker-Plate TMCP Steel

High capacity container carrier has been considered for many decades to transport the more containers at the same time. Therefore, it is required for high capacity container ship to be applied thicker plate to accomodate a mumber of containers compared to that of general container ship. To increase productivity of welding, new welding process should be considered. A representive process for increase of weld productivity is EGW(Electrode Gas Welding) process. Both sides EGW process was evaluated for thicker-plate TMCP Steel. From the test result, it is considered that this process can be applied, showing satisfaction of mechanical properties such as tensile strength and impact property.
