Abstract The corrosion of T91/316L dissimilar weld seam in high-speed flowing liquid lead-bismuth eutectic alloy (LBE) is an important challenge for the future application of T91 and 316L steels in nuclear industry. In this paper, the corrosion test of T91/316L dissimilar weld seams obtained by using three different welding wires (ER309L, ER316L and ERNiCr-3) in 550 ℃ high-speed flowing liquid LBE (relative flow rate of 2.98 m/s) was carried out in a self-designed rotary corrosion device. After being corroded for 300 h, 600 h and 900 h, the surface of all weld seams showed obvious directionality. The corrosion mechanism of weld seam in the high-speed flowing liquid LBE is mainly the dissolution and migration of Fe, Cr and Ni elements in the weld matrix and Pb, Bi, and O elements in the LBE. Due to the different solubility of different elements and the different stability of oxide phases, a double-layer structure consisting of a loose outer oxide layer and a dense inner oxide layer was finally formed on the surface of weld seam. The corrosion resistance of weld seam by using 309L welding wire in the high-speed flowing LBE was the best, followed by 316L welding wire, and that using NiCr-3 welding wire was the worst. The weld seam after heat treatment showed better corrosion resistance to high-speed flowing LBE.
