摘要 采用低碳低合金成分的FOXDCMV焊条对G17CrMoV5-10材料进行堆焊后,选择不同的焊后热处理方式,分析和讨论母材与熔敷金属的硬度、组织变化及对比。结果表明,焊后进行690℃消应后,母材及熔敷金属硬度满足标准要求,熔敷金属区硬度略低于母材;焊后经过950℃油淬+700℃重新调质热处理,母材硬度满足标准要求,而熔敷金属硬度则低于标准要求。 After DCMV FOX welding rod with low carbon and low alloy composition was used for build-up welding of G17CrMoV5-10 material, different post weld heat treatment processes have been adopted, and the hardness and microstructure of the base metal and deposited metal have been analyzed and compared. The results show that after post weld stress relief at 690℃, the hardness of the base metal and deposited metal meet the standard requirement, and after post weld oil quenching at 950℃ and renewed quenching and tempering heat treatment at 700℃, the hardness of base metal meet the standard requirement, and the hardness of deposited metal is lower than the standard requirement.
