The cryogenic high manganese steel is designed for tanks that transport liquefied natural gas, which has increased in demand globally. For this purpose, high manganese steel weld wire with ni added for Flux Cored Wire welding was welded under various heat input conditions. Then, a tensile test was measured to evaluate the mechanical properties. As a result, the heat input condition satisfying the required yield strength was 1.5 kJ. The reason for this phenomenon is that a small amount of Cu contained in the base metal and the welding rod is generated in grain boundaries of Cu2O during solidification, causing liquefaction cracking.
