Study on corrosion of welded steel for LBE-cooled fast reactors

► we investigate the corrosion behavior of welded HCM12A in liquid LBE at 650 °C. ► Thickness value of oxide layer is higher for weld zones than BM. However, thickness of oxide layer among weld zones is nearly the same. Even though welding methods and welding parameters speed were different. ► Hardness value is much higher for the weld zones than BM before corrosion test.
