Liquid sodium is used as the coolant for liquid metal fast breeder reactor. The 2 1/4Cr-1Mo steel is used as structural material for evaporator and SUS F321 steel is used for super heater of steam generator of "Monju", a prototype fast breeder reactor in Japan. The trial manufacture of small sodium loop made of SUS 316 steel and a study on the sodium corrosion of explosive plugged part are already reported by us. Study on the sodium corrosion of arc welded part of SUS 321 steel, SUS 304 steel and 2 1/4Cr-1Mo steel is reported in this paper. Measurement of weight loss and analysis by X-ray photoelectron spectrum are conducted for the corroded specimen. Effect of welding on the corrosion characteristic of these materials is not evidently observed.
