摘　　要：基于摩擦叠焊技术特点,研究不同的焊后热处理工艺对水下摩擦叠焊焊接接头质量的影响。结果表明:焊后热处理能够明显细化水下摩擦叠焊焊接接头的组织晶粒,降低焊接接头的硬度,提高拉伸强度和弯曲性能。Based on the characteristics of friction welding technology, the influence of the post weld heat treatment process on the friction welding joint underwater is analyzed. The results show that the microstructure of the friction welded joint can be refined, and the hardness can be reduced, the tensile strength and bending properties also can be improved by post weld heat treatment progress.
