As the critical load-bearing part of launch vehicle tank, the Y-shaped transition ring is manufactured by integral forging process currently, and it puts forward very high requirements for the forming precision, microstructure and welding performance of the integral forged transition ring. In this paper, the integral forging process for the Y-shaped transition ring of large launch vehicle tank is studied. Microstructure, mechanical properties and welding performance of the transition ring are analyzed. Improvement measures for integral forging process of large Y-shaped transition ring are proposed.
