Microstructures and Mechanical Properties of Butt Joint of Dissimilar Steels 15Ni3CrMoV and 10Ni5CrMoV
摘 要
采用脉冲TIG焊及手工电弧焊相结合对15Ni3CrMoV钢与10Ni5CrMoV钢进行双边开坡口的对接焊,对异种钢对接接头的显微组织、拉伸性能、冲击韧性和显微硬度等进行了研究。结果表明:异种钢对接接头焊缝区的组织呈典型的树枝晶特征,手工电弧焊对接接头的焊缝晶粒呈垂直生长的特点,而脉冲TIG焊对接接头的焊缝晶粒则呈水平生长的特点;对接接头室温拉伸断裂位置均在焊缝区,热影响区的硬度最大;脉冲TIG焊对接接头的抗拉强度和冲击韧性均高于手工电弧焊的。
Abstract
Butt welding was carried out on 15Ni3CrMoV steel and 10Ni5CrMoV steel by TIG(tungsten inert gas) welding and manual arc welding, the microstructure, tensile property, impact property and hardness of the butt joint were studied. The results show that typical dendrite microstructure was found in the weld seam of dissimilar steels butt joint, the grains in weld seam of manual arc welding butt joint exhibit the characteristic of vertical growth, while the grains in weld seam of pulse TIG welding butt joint exhibit the characteristic of horizontal growth. Tensile fracture position of the butt joint at room temperature located in weld seam zone, and the hardness of heat-affected zone is highest. Compared with manual arc welding butt joint, the pulse TIG welding butt joint has higher tensile strength and impact toughness.
